This book discusses categorical data analysis and its implementation with the SAS System. Both nonparametric methods and model-based parametric methods are discussed. Specific topics include association in 2-by-2 tables, Mantel-Haenszel methods for assessing association in sets of tables, logistic regression for dichotomous and polytomous responses, weighted least squares regression, repeated measurements analysis, and loglinear models. Special topics include bioassay and the analysis of categorized time-to-event data. The methodology is illustrated with practical examples using the FREQ, LOGISTIC, CATMOD, and GENMOD procedures. 
Supports releases 6.07 and higher of SAS software.

Statisticians and researchers will find Maura Stokes, Charles Davis, and Gary Koch's Categorical Data Analysis Using the SAS System, Second Edition, to be a useful discussion of categorical data analysis techniques as well as an invaluable aid in applying these methods with SAS. Practical examples from a broad range of applications illustrate the use of the FREQ, LOGISTIC, GENMOD, and CATMOD procedures in a variety of analyses. Other procedures discussed include the PHREG and NPAR1WAY procedures. Topics discussed include assessing association in contingency tables and sets of tables, logistic regression and conditional logistic regression, weighted least squares modeling, repeated measurements analyses, log-linear models, and bioassay analysis. The second edition has been revised for use with SAS 8. New topics include additional exact tests, generalized estimating equations, use of the CLASS statement in the LOGISTIC procedure, exact logistic regression using the LOGISTIC procedure, and comparisons of the use of subject-specific models versus population-averaged models.
