After more than one decade of intensive research, the litera­ ture has reached a level of maturity that calls for a systematic and accessible exposition of the main results and methods. Such an exposition is the aim of the book. Count data models have found their way into

Hybrid models exists as well. A third category of models addresses the issue of a dependent count process.
