Categorical Data Analysis Using the SAS System

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.
