Financial Modelling in Python (The Wiley Finance Series) Review

Financial Modelling in Python (The Wiley Finance Series)
Average Reviews:

(More customer reviews)
I am a quant, dealing with financial modeling on daily basis, and this book is the worst that I have ever used.
I had great expectations because I love python but I was so disappointed.
It is really complicated to use the CD and the explanations are so poor.
The book is mostly full with code without real explanations.
Don't buy this book and don't waste your money. It is very bad.
I dont like to write bad reviews, actually it is my first time but this book is very bad.

"Fletcher and Gardner have created a comprehensive resource that will be of interest not only to those working in the field of finance, but also to those using numerical methods in other fields such as engineering, physics, and actuarial mathematics. By showing how to combine the high-level elegance, accessibility, and flexibility of Python, with the low-level computational efficiency of C++, in the context of interesting financial modeling problems, they have provided an implementation template which will be useful to others seeking to jointly optimize the use of computational and human resources. They document all the necessary technical details required in order to make external numerical libraries available from within Python, and they contribute a useful library of their own, which will significantly reduce the start-up costs involved in building financial models. This book is a must read for all those with a need to apply numerical methods in the valuation of financial claims."–David Louton, Professor of Finance, Bryant University
This book is directed at both industry practitioners and students interested in designing a pricing and risk management framework for financial derivatives using the Python programming language.
It is a practical book complete with working, tested code that guides the reader through the process of building a flexible, extensible pricing framework in Python. The pricing frameworks' loosely coupled fundamental components have been designed to facilitate the quick development of new models. Concrete applications to real-world pricing problems are also provided.
Topics are introduced gradually, each building on the last. They include basic mathematical algorithms, common algorithms from numerical analysis, trade, market and event data model representations, lattice and simulation based pricing, and model development. The mathematics presented is kept simple and to the point.
The book also provides a host of information on practical technical topics such as C++/Python hybrid development (embedding and extending) and techniques for integrating Python based programs with Microsoft Excel.
The book is accompanied by a CD ROM containing a code library; and a companion website www.wiley.com/go/fletcher_python which will feature code-based updates relating to Python 3.0.

Modeling Reactive Systems With Statecharts : The Statemate Approach Review

Modeling Reactive Systems With Statecharts : The Statemate Approach

Statecharts allow you to model systems without the state explosions that you encounter with regular finite state machines. Harel invented and nurtured the field, and has now come out with an excellent overview of how to make it all work.

The book provides a detailed description of a set of languages for modeling reactive systems, which underlies the STATEMATE toolset. The approach is dominated by the language of Statecharts, used to describe behavior, combined Activity-charts for describing activities (i.e., the functional building blocks--capabilities or objects) and the data that flows between them. These two languages are used to develop a conceptual model of the system, which can be combined with the system's physical, or structural model, described in a third language--Module-charts. The three languages are highly diagrammatic in nature, constituting full-fledged visual formalisms, complete with rigorous semantics. They are accompanied by a Data Dictionary for specifying additional parts of the model that are textual in nature.

Mathematical Modeling of Physical Systems: An Introduction (Engineering & Technology) Review

Mathematical Modeling of Physical Systems: An Introduction (Engineering and Technology)

This book has a really nice, diversified selection of topics, and is quite readable. However, out of the three parts I looked at carefully, it is clear that one (the example on Global Positioning System) has a mathematical mistake (equations 3.13a,b,c), when solving a set of equations simultaneously in which all reference to y and z squared terms was lost on the right side of the equation. I think the book does well in explaining the big ideas, but one had better check all the details of the calculations before accepting them.

Mathematical Modeling of Physical Systems provides a concise and lucid introduction to mathematical modeling for students and professionals approaching the topic for the first time. It is based on the premise that modeling is as much an art as it is a science--an art that can be mastered only by sustained practice. To provide that practice, the text contains approximately 100 worked examples and numerous practice problems drawn from civil and biomedical engineering, as well as from economics, physics, and chemistry. Problems range from classical examples, such as Euler's treatment of the buckling of the strut, to contemporary topics such as silicon chip manufacturing and the dynamics of the human immunodeficiency virus (HIV). The required mathematics are confined to simple treatments of vector algebra, matrix operations, and ordinary differential equations. Both analytical and numerical methods are explained in enough detail to function as learning tools for the beginner or as refreshers for the more informed reader. Ideal for third-year engineering, mathematics, physics, and chemistry students, Mathematical Modeling of Physical Systems will also be a welcome addition to the libraries of practicing professionals.

Introduction to Mathematical Modeling Using Discrete Dynamical Systems Review

Introduction to Mathematical Modeling Using Discrete Dynamical Systems

This book introduces Mathematical Modeling without requiring a background in differential equations. I think it does so effectively, although I agree with the previous reviewer that some of the examples are trivial. If used as part of a college course, the instructor really ought to assign computational projects.
Some of the models presented in the book are very similar, but that is not an issue with the book. It seems like an effective way to get students to figure out on their own how similar models are connected. In later chapters, function families are introduced that show how the behavior of interest can be analyzed more generally. Working with pencil and eraser, I prefer easy models. In practical applications, it's all going to be done by a computer anyway.
There are other Mathematical Modeling books that will be more challenging. However, introducing these concepts in ways that require differential equations and linear algebra may just make it more difficult to focus on the new concepts. If you understand the ideas in these simple models, you will also recognize them in more advanced models.
