I think this textbook is an excellent introduction to a large set of models for binary, multinominal, count, duration, and censored or truncated data. It is excellent for a survey course on such models or as an introduction to generalized linear modeling tools. The level is that of a second-semester or second-year graduate student in social sciences (sociology, demography, psychology, communications, marketing and management, etc.) who already knows linear regression. For that audience, the book strikes a very good balance of rigor and relevance.
The book is not technical enough to be used in graduate econometrics courses. But I expect the book being very useful as a textbook in advanced undergraduate econometrics courses or as additional reading to graduate economics students trying to get a more practical understanding of how and when to use these models and how to interpret the estimates.
