Packed with step-by-step examples, this book shows you how to use the SAS System to perform logistic, probit, and conditional logistic regression analyses. This book enables statisticians, researchers, and new students to learn from the set of examples so that they can perform their own analyses and produce and understand the output. This book focuses on the LOGISTIC procedure but also contains examples that use the CATMOD, GENMOD, PHREG, and PROBIT procedures in SAS/STAT software.
