ABSTRACT
SAS, originally an acronym for Statistical Analysis System, comprises a broad range of software modules that can be added to the basic system, known as BASE SAS. Here our focus is on the SAS/STAT module in addition to the main features of the base system. Where we use any features of SAS that require additional modules, this will be indicated in the text. As of version 9.3 of SAS, there are sufficient graphical capabilities in the BASE and STAT modules that the SAS/GRAPH module will not be needed by most users.
