Analyzing Categorical Data by Jeffrey S. Simonoff.
Mentioned in My Intro to Multiple Classification… but thought it merited a more prominent mention.
From the webpage:
Welcome to the web site for the book Analyzing Categorical Data, published by Springer-Verlag in July 2003 as part of the Springer Texts in Statistics series. This site allows access to the data sets used in the book, S-PLUS/R and SAS code to perform the analyses in the book, some general information on statistical software for analyzing categorical data, and an errata list. I would be very happy to receive comments on this site, and on the book itself.
Data sets, code to duplicate the analysis in the book and other information at this site.
