Risk Analysis of Complex and Uncertain Systems (International Series in Operations Research & Management Science) Review

Risk Analysis of Complex and Uncertain Systems (International Series in Operations Research and Management Science)
Average Reviews:

(More customer reviews)
This is an excellent, approachable read for any risk manager; understanding its examples requires only elementary probability, statistics and calculus, though the foundations are much deeper. The author uses direct language, and does not hesitate to declare a fashionable risk analysis technique "worse than useless." The author shows how not to do risk analysis, using simple but devastating examples to illustrate the weaknesses of prioritized investments, subject matter expert opinion, risk matrices and qualitative risk assessments, and the independence assumption. Then, case studies present constructive examples of good practice. Refreshingly, this text clearly distinguishes between threats from Mother Nature, and those posed by an intelligent adversary. There is unevenness, because this is an edited ensemble of papers originally published in a variety of technical journals; however, this is also a strength, because the appeal and scholarship underlying biological, engineering, and social science examples is broad. This is not a how-to guide, and won't help fill in a blank page risk analysis; however, this is an excellent source for the skeptical consumer of contemporary risk management advice and products, and hopefully will have some influence with policy makers who are the source of simplistic and dangerous guidance.

In Risk Analysis of Complex and Uncertain Systems acknowledged risk authority Tony Cox shows all risk practitioners how Quantitative Risk Assessment (QRA) can be used to improve risk management decisions and policies. It develops and illustrates QRA methods for complex and uncertain biological, engineering, and social systems - systems that have behaviors that are just too complex to be modeled accurately in detail with high confidence - and shows how they can be applied to applications including assessing and managing risks from chemical carcinogens, antibiotic resistance, mad cow disease, terrorist attacks, and accidental or deliberate failures in telecommunications network infrastructure. This book was written for a broad range of practitioners, including decision risk analysts, operations researchers and management scientists, quantitative policy analysts, economists, health and safety risk assessors, engineers, and modelers.

A Practical Guide to Ecological Modelling: Using R as a Simulation Platform Review

A Practical Guide to Ecological Modelling: Using R as a Simulation Platform
Average Reviews:

This is an awesome book, primarily about modeling, less about R. There are many "introduction to R" books available, perhaps too many.
This book and its accompanying software in the several R packages are an excellent way to both learn the material, and to explore other related problems.
Naturally, the course is primarily what you bring to it. Soetaert and Hermann provide a comprehensive introduction, heavily illustrated by examples. The mathematics is excellent, and essential.

Mathematical modelling is an essential tool in present-day ecological research. Yet for many ecologists it is still problematic to apply modelling in their research. In our experience, the major problem is at the conceptual level: proper understanding of what a model is, how ecological relations can be translated consistently into mathematical equations, how models are solved, steady states calculated and interpreted. Many textbooks jump over these conceptual hurdles to dive into detailed formulations or the mathematics of solution. This book attempts to fill that gap. It introduces essential concepts for mathematical modelling, explains the mathematics behind the methods, and helps readers to implement models and obtain hands-on experience. Throughout the book, emphasis is laid on how to translate ecological questions into interpretable models in a practical way.The book aims to be an introductory textbook at the undergraduate-graduate level, but will also be useful to seduce experienced ecologists into the world of modelling. The range of ecological models treated is wide, from Lotka-Volterra type of principle-seeking models to environmental or ecosystem models, and including matrix models, lattice models and sequential decision models. All chapters contain a concise introduction into the theory, worked-out examples and exercises. All examples are implemented in the open-source package R, thus taking away problems of software availability for use of the book. All code used in the book is available on a dedicated website.

Bayesian Data Analysis, Second Edition (Chapman & Hall/CRC Texts in Statistical Science) Review

Bayesian Data Analysis, Second Edition (Chapman and Hall/CRC Texts in Statistical Science)
Average Reviews:

(More customer reviews)
Note, this is a review of the first edition.
Overview
This book was the textbook used at the University of Wisconsin-Madison for the graduate course in Bayesian Decision and Control I during the fall of 2001 and 2002. It strikes a good balance between theory and practical example, making it ideal for a first course in Bayesian theory at an intermediate-advanced graduate level. Its emphasis is on Bayesian modeling and to some degree computation.
Prerequisites
While no Bayesian theory is assumed, it is assumed that the reader has a background in mathematical statistics, probability and continuous multi-variate distributions at a beginning or intermediate graduate level. The mathematics used in the book is basic probability and statistics, elementary calculus and linear algebra.
Intended audience
This book is primarily for graduate students, statisticians and applied researchers who wish to learn Bayesian methods as opposed to the more classical frequentist methods.
Material covered
It covers the fundamentals starting from first principles, single-parameter models, multi-parameter models, large sample inference, hierarchical models, model checking and sensitivity analysis (model checking and sensitivity analysis are especially well covered), study design, regression models, generalized linear models, mixture models and models for missing data. In addition it covers posterior simulation and integration using rejection sampling and importance sampling. There is one chapter on Markov chain Monte Carlo simulation (MCMC) covering the generalized Metropolis algorithm and the Gibbs sampler.
Over 38 models are covered, 33 detailed examples from a wide range of fields (especially biostatistics). Each of the 18 chapter has a bibliographic note at the end. There are two appendixes: A) a very helpful list of standard probability distributions and B) outline of proofs of asymptotic theorems.
Sixteen of the 18 chapters end with a set of exercises that range from easy to quite difficult. Most of the students in my fall 2001 class used the statistical language R to do the exercises.
The book's emphasis is on applied Bayesian analysis. There are no heavy advanced proofs in the book. While the proofs of the basic algorithms are covered there are no algorithms written in pseudo code...Additional books of related interest
1) Statistical Decision Theory and Bayesian Analysis, James Berger, second edition. Emphasis on decision theory and more difficult to follow than Gelman's book. Covers empirical and hierarchical Bayes analysis. More philosophical challenging than Gelman's book.
2) Monte Carlo Statistical Methods, Robert and Casella. Very mathematically oriented book. Does a good job of covering MCMC.
3) Monte Carlo Methods in Bayesian Computation, Ming-Hui Chen, Qi-Man Shao, Joseph George Ibrahim. An enormous number of algorithms related to MCMC not covered elsewhere. If you need MCMC and need an algorithm to implement MCMC this is the book to read.
4) Monte Carlo Strategies in Scientific Computing, Jun S. Liu. Covers a wide range of scientific disciplines and how Monte Carlo methods can be used to solve real world problems. Includes hot topics such as bioinformatics. Very concise. Well written, but requires effort to understand as so many different topics are covered. This book is my most often borrowed book on Monte Carlo methods. Jun S. Liu is a big gun at Harvard.
5) Probabilistic Networks and Expert Systems. Cowell, Dawid, Lauritzen, Spiegelhalter. Covers the theory and methodology of building Bayesian networks (probabilistic networks).

Incorporating new and updated information, this second edition of THE bestselling text in Bayesian data analysis continues to emphasize practice over theory, describing how to conceptualize, perform, and critique statistical analyses from a Bayesian perspective. Its world-class authors provide guidance on all aspects of Bayesian data analysis and include examples of real statistical analyses, based on their own research, that demonstrate how to solve complicated problems. Changes in the new edition include:
Stronger focus on MCMC
Revision of the computational advice in Part III
New chapters on nonlinear models and decision analysis
Several additional applied examples from the authors' recent research
Additional chapters on current models for Bayesian data analysis such as nonlinear models, generalized linear mixed models, and more
Reorganization of chapters 6 and 7 on model checking and data collectionBayesian computation is currently at a stage where there are many reasonable ways to compute any given posterior distribution. However, the best approach is not always clear ahead of time. Reflecting this, the new edition offers a more pluralistic presentation, giving advice on performing computations from many perspectives while making clear the importance of being aware that there are different ways to implement any given iterative simulation computation. The new approach, additional examples, and updated information make Bayesian Data Analysis an excellent introductory text and a reference that working scientists will use throughout their professional life.

As an instructor who uses this book to teach MBA students, I consider this as a valuable resource.
However, I am concerned that too many examples have been put together, without much intuition and insights in what justifies the models used for the simulation and how to effectively design the simulation.
As a result, student learns how to produce results for certain cases, but they don't know how to adjust it if assumptions change.

Great book! Simple and understandable language. Nice graphs to explain the theory. All the statements are referenced and or supported with examples. Overall the book has a lot of depth as well; so it will be useful for your introduction to prediction models, but also later on. I was getting lost in all the publications and statistical study books, until I found this book.

Data Mining Techniques in CRM: Inside Customer Segmentation Review

Data Mining Techniques in CRM: Inside Customer Segmentation
Average Reviews:

(More customer reviews)
I recently finished reading Data Mining Techniques in CRM: Inside Customer Segmentation. It is a very didactic book written by Tsiptsis and Chorianopoulos. The authors did a very good job in vulgarizing data mining concepts for the reader. That means nearly no formula. But don't misunderstand me, this is not a book only for beginner. Some deep concepts of data mining are presented. The only particularity is that everything is explained with words and pictures. I really appreciated the approach taken by the authors.
The first part of the book explains data mining concepts. Techniques such as clustering, PCA (Principal Component Analysis) and decision trees are introduced. Since clustering is the most used technique in CRM (Customer Relationship Management), it has a particular focus from the authors. Specific topics such as evaluating the clustering results or profiling are discussed. A very interesting chapter is the one showing examples of data marts in CRM applications (retailers, telco and retail banking).
The second part of the book focuses on CRM applications such as segmentation, cross/up-selling, churn, etc. Full chapters are devoted to customer segmentation in banking, retail and telco. These chapters really give detailed information for such projects (data to consider, aggregations, important factors, result interpretation, etc.). It is clear that the authors have a strong experience in CRM.
To conclude, this is an excellent book for any data miner or anybody involved in CRM. The text is clear and pictures are well done (and funny which is rare enough to be mentioned). From basic to advanced topics, the book is a very pleasant journey inside data mining with a clear focus on customer segmentation. Really advised if you're not a fan of formulas.

Bayesian Core: A Practical Approach to Computational Bayesian Statistics (Springer Texts in Statistics) Review

Bayesian Core: A Practical Approach to Computational Bayesian Statistics (Springer Texts in Statistics)
Average Reviews:

(More customer reviews)
I have used 'Bayesian Core' to teach Bayesian statistics to a class of Masters students majoring in finance, statistics or business with an undergraduate mathematics/statistics background and found it to be quite a good book for this purpose. I would have to disagree though with the previous reviewer (A.L.H Mayne) and suggest that this book could also be good for a practitioner, provided they have some prior statistical and mathematical understanding. A limitation for self guided study is the absence of solutions to exercises or hints necessary to ensure understanding for some of the exercises. I would also have to disagree with the previous reviewer over what is or what is not discussed in the book! The statement "conjugacy is mentioned in exercise 2.10 on page 22 with no discussion" is simply not true, the entire page preceding this exercise discusses conjugate priors in particular and they are subsequently used and outlined in the following chapters. There is also considerable attention paid in the book to the use of improper priors, in particular with respect to the implications of using improper priors for the estimation of Bayes factors (Chapter 3). A more thorough description of Jeffrey's Lindley paradox could be provided but a more complete discussion of this seems outside the scope of the book. Similarly, outlining the "historical antecedents ..." and more "...theory" about Jeffrey's prior than what is already provided, while interesting and important in its own right, is not necessarily mandatory reading for the student or practitioner who seeks a practical introduction to the Bayesian approach. To highlight "The implementation of the Monte Carlo method is straightforward" without adding the next few words used in the book "at least on a formal basis" seems terribly insincere and pedantic.
What the book is? The book presents a Bayesian approach to the analysis of topics commonly analysed in statistics designed to allow the reader to quickly grasp the essential elements of Bayesian principles and to put this into practice with examples using R code (simple computing syntax) provided on the website. There are surely limitations of this approach (albeit also acknowledged by the authors!) namely a less than full treatment of topics and of theoretical derivations for approaches. Some of the exercises are also difficult and these exercises could well do with hints being provided or a short statistical annotation.

This Bayesian modeling book is intended for practitioners and applied statisticians looking for a self-contained entry to computational Bayesian statistics. Focusing on standard statistical models and backed up by discussed real datasets available from the book website, it provides an operational methodology for conducting Bayesian inference, rather than focusing on its theoretical justifications. Special attention is paid to the derivation of prior distributions in each case and specific reference solutions are given for each of the models. Similarly, computational details are worked out to lead the reader towards an effective programming of the methods given in the book.

Handbook of Statistical Analysis and Data Mining Applications Review

Handbook of Statistical Analysis and Data Mining Applications
Average Reviews:

(More customer reviews)
The "Handbook of Statistical Analysis & Data Mining Applications" is the finest book I have seen on the subject. It is not only a beautifully crafted book, with numerous color graphs, chart, tables, and screen shots, but the statistical discussion is both clear and comprehensive.
The text does not use only one statistical data mining application to display examples, but provides a rather thorough training in the use of both SAS-Enterprise Miner and STATISTICA Data Miner. A section on SPSS Clementine is also provided, giving comparisons between the various packages. Also employed are STATISTICA's C&RT, CHAID, MARSpline, and other data mining and graphical analytic tools.
The text does not burden the typical data mining researcher with the internals of how the various tools work. It is therefore not steeped in equations. Some are to be found, of course, but the emphasis is on understanding the concepts involved and on how to apply these concepts to real data - which is provided to the reader in terms of data tutorials. Specialized datasets have been prepared by both authors and outside experts in various areas of inquiry ranging from entertainment, financial, engineering, clinical psychology, dentistry, demographics, medical informatics, meteorology, astronomy, and more. Each tutorial is associated with data stored on either the associated CD that comes with the book, or which can be downloaded from a companion web site. Worked out examples of how to use data mining techniques on such data is provided to help the reader gain a solid feel for the data mining enterprise. The final third of the book is devoted to a partial selection of the available tutorials. The two earlier chapters demonstrate how to use data mining software for the analysis of data.
I highly recommend this work to anyone having an interest in data mining. I might also add that the Amazon price of $72.37 is truly excellent for an 864 page academic text, having full color tables and screen shots on some one-third of the pages, plus a CD. A bargain indeed.

Bayes and Empirical Bayes Methods for Data Analysis, Second Edition Review

Bayes and Empirical Bayes Methods for Data Analysis, Second Edition
Average Reviews:

(More customer reviews)
This book features a deep and focused lesson on Bayes and Empirical Bayes Methods. It goes through the key topics as conjugate priors, MCMC methods (non iteratives and iteratives as the well known Gibbs samplining and metropolitis hastings algorithms), model selection methods (as bayes factor) and issues related as model robusteness.
The Approach is increasingly formal and deeply complex, allowing for getting the basics or diving into more complex knowledge according to your former background. You need at least a good understanding of Frequentist statistic to be able to follow the reasonings. Each chapter allow you to stop at some point without losing the thread. Last part of the book is in fact deep knowledge demanding.
The most interesting point of this book according to my very limited statistics background is that it makes good comparations with the frequentist approach (classical approaches as confidence intervals and point estimators), checking performance of either method. Even, it features some combination of both approaches getting some bayessian intervals.
As a negative point, I would say that examples are hard to follow for someone with limited bakground and too much complex. They really do not clear me up enough.
All in all, is a very profitable book for jumping into bayesian methods.

This book was recommended highly to me by a former university professor (and now consultant). It exceeds my expectations. The figures and acompanying explanations are very clear, as is the language throughout. Visualizing Data discusses several tools with which I was not familiar, and clarifies tools that I thought I understood (including box plots). I have taken several university statistics classes, but I believe this book would help anyone involved in displaying or interpreting data. A picture may be worth a thousand words, but when your business depends on it, a well-defined plot or graph can be worth much more. Visualizing Data enables you to produce well-defined plots and graphs with confidence.

Interactive Data Visualization: Foundations, Techniques, and Applications
Average Reviews:

(More customer reviews)
Had to get this overpriced book for an Info Viz class. Be aware that this book is much more of a technical book than a design book. There's a ton of information contained in here, but I also found a surprising amount of quality issues.
First, the flow of the book seems completely off, diving into highly technical material in the second chapter, then pulling back into high level concepts in later chapters. Also, many of the images are not of the quality I would expect from a text book. Many are blurry or scaled inappropriately, given the amount of detail they contain. Finally, there are some glaring mistakes in the copy. For instance, at the end of one section of the book, placeholder notes from the authors of what should be written is included instead of the actual final copy! Where's the editor? Was it rushed to print?
Given the price, I expected a much higher level of quality. Despite the problems listed above, the text could be useful resource for anyone interested in the nuts and bolts of data visualization.

Bayesian Adaptive Methods for Clinical Trials (Chapman & Hall/CRC Biostatistics Series) Review

Bayesian Adaptive Methods for Clinical Trials (Chapman and Hall/CRC Biostatistics Series)
Average Reviews:

(More customer reviews)
In the pharmaceutical industry adaptive designs are currently the rage because of their many potential advantages due to their flexibility. It allows you to stop early for efficacy or futility. It can do drug dose selection more easily and may have patients on inferior treatment for smaller amounts of time. There have already been four or five books published from the frequentist point of view. This is the first serious text on adaptive designs using the Bayesian approach. Pharmaceutical companies including Johnson and Johnson, Eli Lilly, Pfizer, Merck, Novartis, Novo Nordisk, Millennium, AMAG and GlaxoSmithKline have all been successful at running adaptive trials. Merck for example has already completed more than 40 adaptive design trials. Such trials can be done in phase II, phase III or a combining of phases II and III in a single adaptive trial. Merck claims to have completed over 40 adaptive trials. The M D Anderson Medical Center at UT Houston runs hundreds of adaptive trials (all as far as I know using the Bayesian methodology). Don Berry runs the biostatistics group at M D Anderson and he and his son scott own a consulting group that helps companies run Bayesian adaptive designs. Eli Lilly has been one of their clients on a drug trial and Biosense Webster, a J& J company, used them for a Bayesian trial on one of their ablation catheters. Scott Berry isone of the authors of this book and a lot of the book is devoted to work of Berry first at Duke and then later at M D Anderson and Berry Consultants.
Adaptive designs have logistic problems but companies have been able to overcome the problems motivated by the overall time and money saving benefits. All types of studies are illustrated from phase I through phase III and the examples are real and practical. Even when taking the Bayesian approach issues of frequentist properties for the designs comes up. Missing data, multiple testing, type I error and power of the test conditional and unconidtional are important when the frequentist approach is applied. The authors admit that both frequentist and Bayesian properties for a design are important and can be evaluated through simulation.
Although adaptive designs can be implemented effectively using either the Bayesian or the frequentist approaches. But Bayesian trials are a little more natural and simpler. This is the right book to get if you are interested in Bayesian methods.

I think Fishman's book is one of the best introduction to Monte Carlo methods, simulation and pseudo-random number generation. It is also a great reference. However if one is interested in the history of Monte Carlo including its early development in particle physics I recommen the old monograph by Hammersley and Handscomb which also does a great job at introducing the various variance reduction techniques. This is an aspect of the Monte Carlo method that Fishman does not address. It was more important in the days when computers were slow but it still has applications with certain intensive modern computing problems such as Markov Chain Monte Carlo.

Barbara Byrne manages to make a very complicated topic seem manageable and understandable. This book is ideal for people familiar with the basics of psychology statistics, but relatively new at structural equation modeling. My only complaints are that the index is a bit sparse, so I found myself thumbing through the book frequently; and sometimes the details of how to apply the concepts directly to EQS commands were left a bit unclear. However, overall this was an excellent starter book for structural equation newbies!

The software Lisrel was developed to model and analyze data using structural equation models which involve the introduction of latent variables. Although this topic has historically been most commonly used in the social sciences including psychology and sociology, it is finding a wide range of applications as statisticians encounter more and more problems where it is appropriate to use latent variables.
Bollen provides a thorough treatment of the topic that has advanced some since the publication of the book . This is still the best source for a detailed account of the methods. Bengt Meuthen at UCLA was one of the pioneers of the methodology and his books and papers provide good additional sources for the reader who wants to understand the theory and the software tools.

Analysis of Ordinal Categorical Data Alan Agresti Statistical Science Now has its first coordinated manual of methods for analyzing ordered categorical data. This book discusses specialized models that, unlike standard methods underlying nominal categorical data, efficiently use the information on ordering. It begins with an introduction to basic descriptive and inferential methods for categorical data, and then gives thorough coverage of the most current developments, such as loglinear and logit models for ordinal data. Special emphasis is placed on interpretation and application of methods and contains an integrated comparison of the available strategies for analyzing ordinal data. This is a case study work with illuminating examples taken from across the wide spectrum of ordinal categorical applications. 1984 (0 471-89055-3) 287 pp. Regression Diagnostics Identifying Influential Data and Sources of Collinearity David A. Belsley, Edwin Kuh and Roy E. Welsch This book provides the practicing statistician and econometrician with new tools for assessing the quality and reliability of regression estimates. Diagnostic techniques are developed that aid in the systematic location of data points that are either unusual or inordinately influential; measure the presence and intensity of collinear relations among the regression data and help to identify the variables involved in each; and pinpoint the estimated coefficients that are potentially most adversely affected. The primary emphasis of these contributions is on diagnostics, but suggestions for remedial action are given and illustrated. 1980 (0 471-05856-4) 292 pp. Applied Regression Analysis Second Edition Norman Draper and Harry Smith Featuring a significant expansion of material reflecting recent advances, here is a complete and up-to-date introduction to the fundamentals of regression analysis, focusing on understanding the latest concepts and applications of these methods. The authors thoroughly explore the fitting and checking of both linear and nonlinear regression models, using small or large data sets and pocket or high-speed computing equipment. Features added to this Second Edition include the practical implications of linear regression; the Durbin-Watson test for serial correlation; families of transformations; inverse, ridge, latent root and robust regression; and nonlinear growth models. Includes many new exercises and worked examples. 1981 (0 471-02995-5) 709 pp.

In my opinion, Malcolm Haddon has managed a "tour de force" with this book. He not only covered most of the modern methods of quantitative analysis and modelling in fisheries science but he did so in a clear and relatively simple language. His book is approachable to all biologists with a basic understanding of mathematics and statistics. Yet, he managed to cover both the theoretical underpinnings of the methods and the practical aspects of their use (options, pitfalls ... etc.). In addition, the book gives MS Excel examples of the methods which should allow those of us who are not programmers to fully appreciate the methods by using them interactively. The Excel spreadsheets are also available for download on two web sites.

As a conventional textbook to be chosen by an academic for classroom use.
1. As a self-study text for someone learning / relearning management science in a spreadsheet environment, you'll find PMSc written with obvious and utter mastery of the subject matter, that's commendable but hardly unique. What is unique are the clarity of the presentation and the lucidity of the abundant examples running throughout. In addition, there is thoroughness in the treatment which effectively anticipates virtually any and all sources of confusion which a student of any stripe might suffer. It is, in my view, wholly autodidactic. There is a subset of this type of user: the individual with a job-specific task which defies current familiarity / skill-level. No sweat! Use the inside-the-front cover material as a functional area task locator to identify "look-alike" situations and then proceed to master all which is required by back-tracing the example to similar situations encapsulated within the many interspersed problems -- for each of which there is a complete Excel solution format.
2. As a management science student's self-help resource with which to cope and to decipher whatever cryptic text was assigned for the course. If you find yourself in this far too common dilemma, take heart, help is well and truly at hand. Skim the TOC, find the relevant chapter and enjoy basking in your fast-welling, new-found competence. PMSc will provide ample basis for warranting a celebration at the local "pub" -- or whatever passes for same in your locale.
3. "As a conventional textbook to be chosen by an academic for classroom use" was the category into which I "fell." To my dismay, I recently found myself assigned, on extremely short notice, to teach a comprehensive course on MS/OR. I found our standard two-volume text decidedly off-putting and could only conclude that my students would likely as well. As my background includes accounting, finance, and computer systems, I knew that I wanted a spreadsheet-based textbook for the course. As at most schools, MS is under fire for "relevance" and "accessibility," compounded here through the "mix" of students for my various sections: MBA, EMBA, and MS/MOT (latter all engineering degreed).
Suffice it to say that the classes proved complete successes: the students petitioned the Dean to have an advanced management science course added to the curriculum which I'm teaching this (fall '98) semester. In addition to covering the chapters / chapter sections omitted from the "introductory" course, we're using PMSc as the primary text with Bodily, Carraway, et al's excellent QBA case book for facilitating the integration of MS with finance, marketing, operations, and strategy.
As a sidebar: Most of my MBA students were from one of our "dedicated" MBA programs. These manager / students have apparently provided many of their subordinates with copies of PMSc. Their experience had regularly been that they were using on Monday the material I had "taught" them on Saturday.
As if this weren't enough praise, I'm using PMSc as a supplemental text in my finance courses because of its lucid and extensive coverage of @RISK and for the extensive finance material provided. This is proving extremely popular with my students.
As you might infer, I think that PMSc is without peer as the best and most effective text for learning how to actually perform REAL management science without tears or undue ancillary learning. I've yet to have a student who was not wildly enthusiastic about PMSc (that's not hyperbole) -- when's the last time you've had THAT experience?
I'd be happy to hear from anyone buying this text -- I really WANT to hear from anyone buying this text who is less than completely satisfied.
