SOFTWARE SUPPLEMENT FOR AN INTRODUCTION TO CATEGORICAL DATA ANALYSIS

This supplement contains information about software for categorical
data analysis and is intended to supplement the material in the second
edition of An Introduction to Categorical Data Analysis, by Alan
Agresti (Wiley, 2007).
## SAS

See Appendix A of "An Introduction to Categorical Data Analysis" (2nd
ed., 2007) for discussion of SAS, and go to **SAS
examples for Intro CDA** for illustrations of SAS for data
sets in this text and to **SAS
examples for CDA** for illustrations of SAS for data sets in
my more advanced text (most of which are also in the introductory
text).
For other examples of various analyses for some examples in "An
Introduction to Categorical Data Analysis", see the useful site set
up by the UCLA
Statistical Computing Center.
## S-Plus, R and others

See **Software for
CDA** for discussion about software for categorical data
analysis. That site is designed for my more advanced text
(Categorical Data Analysis, Wiley 3rd edition 2013) but is relevant
also for the introductory text. In particular, Dr. Laura Thompson has
prepared an excellent, detailed manual (over 250 pages!!) on the use
of S-Plus and R to conduct the analyses shown in my more advanced
book. You can get a copy of this at Laura
Thompson S manual for CDA. Thanks very much to Dr. Thompson for
providing this very helpful resource. In simpler form, Brett Presnell
has many examples of the use of R for categorical data analyses from
teaching a course at the University of Florida from the first edition
of this book, at Brett
Presnell material on R for CDA.
