Along with Gallant's book on nonlinear regression this book is one of the best. It is on an intermediate level and assumes some knowledge of linear regression. Notable unique aspects of the book are (1) good use of geometry, (2) discussion of derivative free methods, (3) use of profile likelihood and profile t plots and (4) measures of degree of nonlinearity of the problem. The authors also provide many real world applications directly from their consulting experience.

These authors were among the researchers that developed these measures of nonlinearity and so that aspect of the book is original and is emphasized in this book more than in others such as Gallant's.

Spectral Analysis and Its Applications is an excellent source for professionals with intermediate time-series statistics skills. It clearly outlines and demonstrates the methods necessary to carry out sound spectral analysis of time-series data and how to use this data for modelling purposes. It is also a great aid and reference for anyone who needs the means to triumph over inexperience and under-education in time-series debates. Four years out of graduate school, I need this book again; I wish I'd bought it sooner.

"How War Came" covers the period roughly from Europe to the beginning of World War II. Of course, the key actor in this period was Hitler; it was his will, more than any other factor, that caused the war to start.

Of course, no one at the time knew that at the time, and this book accounts the diplomatic efforts made by the Britain, France and others to avoid the War. This provides a useful perspective on the history of the time, which tends to focus exclusively on Hitler. Watt has thoroughly researched this period, and provides information that even those who are well-read in the events leading up to the war will learn much from this book.

This book tells of the time between Munich and the declaration of war on Sept. 3, 1939. It is very well done, and the final chapters are dramatic and attention-holding. The author is English, and some of his comments on American politics are not very insightful, but I liked the book and found it well woth reading, even if it is 11 years old.
