This book is organized as follows.

Chapter 1, What’s New in SAS/STAT 9.22, provides information about the changes and enhancements to SAS/STAT software in SAS 9.22. It describes two new procedures and numerous new features.

Chapter 2, this chapter, provides an overview of SAS/STAT software and summarizes related information, products, and services. The remaining introductory chapters ( Chapter 3, Introduction to Statistical Modeling with SAS/STAT Software, through Chapter 17, Introduction to Structural Equation Modeling with Latent Variables, ) provide an introduction to the broad areas covered by SAS/STAT software.

Chapter 18, Introduction to Power and Sample Size Analysis, provides documentation for the Power and Sample Size Application (PSS).

Chapter 19, Shared Concepts and Topics, provides information about topics that are common to multiple procedures. Topics include parameterization of model effects, the EFFECT statement, and the NLOPTIONS statement. Starting in SAS/STAT 9.22, this chapter also documents the following statements that are used for postfitting analysis and are common across many modeling procedures: EFFECTPLOT, ESTIMATE, LSMEANS, LSMESTIMATE, SLICE, STORE, and TEST.

Chapter 20, Using the Output Delivery System, explains the fundamentals of using the Output Delivery System (ODS) to manage your SAS output.

Chapter 21, Statistical Graphics Using ODS, describes the extension to ODS that enables many statistical procedures to create statistical graphics as easily as they create tables.

Subsequent chapters describe the SAS procedures that make up SAS/STAT software. These chapters appear in alphabetical order by procedure name and are organized as follows:

• The "Overview" section provides a brief description of the analysis provided by the procedure.

• The "Getting Started" section provides a quick introduction to the procedure through a simple example.

• The "Syntax" section describes the SAS statements and options that control the procedure.

• The "Details" section discusses methodology and miscellaneous details, such as ODS tables and ODS graphics.

• The "Examples" section contains examples that use the procedure.

• The "References" section contains references for the methodology and for examples of the procedure.

Following the chapters on the SAS/STAT procedures, Appendix A, Special SAS Data Sets, documents the special SAS data sets that are associated with SAS/STAT procedures.
