Multiple Comparisons & Multiple Tests Using the Sas System

Have you ever felt that there was no multiple inference method that fits the particular constraints of your data? Or been overwhelmed by the many choices of procedures? This book solves both dilemmas for you by providing cutting-edge methods, specialized macros, and proven "best bet" procedures. The specialized macros and dozens of real-world examples illustrate solutions for a broad variety of problems that call for multiple inferences. The book also discusses the pitfalls and advantages of various methods, thereby helping you decide which is the most appropriate for your purposes.

If you are a researcher or scientist in pharmaceuticals, engineering, government, or medicine, you will find many methods applied to real data and examples from your field. The book includes specialized code and explanations throughout. It discusses in detail pairwise comparisons and comparisons with a control. Additional topics include general linear contrasts; multiple comparisons of multivariate means; multiple inferences with mixed models, discrete data, and survival analysis. Users with releases of SAS software prior to Version 7 will need to make some modifications.

Supports releases 6.09E and higher of SAS software.
