Categorical Data Analysis
Website for CATEGORICAL DATA ANALYSIS, 2nd edition
For the second edition of Categorical Data Analysis by Alan Agresti
(Wiley, 2002), this site contains (1) information on the use of other
software (such as R and S-plus, Stata, SPSS, StatXact and LogXact) not
covered in Appendix A of the text (which discusses SAS in some
detail), (2) data sets for examples in the form of complete SAS
programs for conducting the analyses, (3) data sets used in some of
the homework exercises, (4) short answers for many of the odd-numbered
exercises, (5) extra exercises, and (6) corrections of errors in early
printings of the book. Also, there's (7) a seminar on the history of
CDA, and (8) a review paper about Bayesian methods for categorical
data analysis.
1. Software for categorical data analyses: Here is a file containing
information and links for several software packages.
Dr. Laura Thompson has prepared a detailed manual on the use of R or S
to conduct all the analyses in the CDA text. You can get a copy of
this excellent resource
at Laura
Thompson R and S manual for CDA. Thanks very much to Dr. Thompson
for providing this manual. For my lower-level text, An Introduction
to Categorical Data Analysis (2nd ed. 2007), an especially useful
resource is the website
of Chris Bilder,
where the link to R has examples of the use of R for most chapters of
the text and the link to Schedule has course notes following the ICDA
text as well as imbedded R code and output. He also has an extremely
useful set of links at the "Link" branch on his menu, including links
to home pages for various courses on categorical data analysis.

the homework exercises for which tables are not shown in the

odd-numbered exercises at the ends of the chapters:

7. The final chapter gives a historical tour of CDA. Here is a
History of CDA seminar that I presented in September, 2009,
to the Boston chapter of the American Statistical Association, with
some discussion at the end of the talk on advances having a Boston
connection. To watch this, enter your email address and click on

discretized copy of my presentation.)
8. I had intended to include a chapter in the second
edition on Bayesian analyses for categorical data analysis (to beef up
the short section in Chapter 15), but the book just became too long.
However, David Hitchcock (Statistics Dept., Univ. of South Carolina)
and I have written a survey paper about such
methods:
- Bayesian
inference for categorical data analysis that appeared in
Statistical Methods and Applications, the Journal of the Italian
Statistical Society, in 2005 (volume 14, pages 297-330). It was
partly a by-product of a very nice summer that I spent in Florence,
Italy.
A somewhat longer version of this paper is
