SAS statements,Procedures and Functions

Posted by www.sas9.blogspot.com on Sunday, December 9, 2007


SAS Statements, Procedures, and Functions SAS documentation can be overwhelming. The software is split into modules (such as BASE, STAT, GRAPH). The online documentation is split into versions and modules, a variety of guides (each organized in a different fashion) and the documentation has undergone several revisions. This guide provides an alphabetical listing of commonly used SAS statements, SAS functions, and SAS procedures. It points to vendor supplied online descriptions of each key word mentioned. No distinction is made between the modules. Most statements and the use of SAS functions must be placed within a data step (i.e. Between a line that begins with data ...; and after other lines... a run; statement.) A data step defines data that can be analyzed by other procedure (or PROC) steps. This guide is an introductory reference. It is not meant to be read as a tutorial. For a well rounded introductory knowledge of SAS the user should be familiar with the following:

Several SAS statements (or syntactic constructs) help to improve the readability of your SAS program.
These are:
Comments (text meant to be read by humans, using * ...; or /* ... */)
RUN;
TITLE
[edit]
SAS Procedures
PROC CORR
PROC FREQ
PROC MEANS (similar to PROC SUMMARY)
PROC PLOT (similar to PROC GPLOT)
PROC PRINT
PROC REG
PROC SORT (should be accompanied by a BY statement)
PROC TTEST
[edit]
SAS Functions
SAS Functions ABS
SAS Functions LENGTH (to work with text (strings) instead of numbers)
SAS Functions MAX
SAS Functions MEAN
SAS Functions MIN
SAS Functions ROUND
SAS Functions SUBSTR (to work with text (strings) instead of numbers)
all SAS Functions (alphabetically) (by categories)

Where are the statistics described? Specific statistical procedures that are not found in the Procedures guide are probably in the SAS/ETS guide (since Time Series are ...?). While somewhat statistical in nature PROC CORR, MEANS, SUMMARY, and FREQ are part of the SAS/BASE module.
Common statistical prcedures not listed here are LOGISTIC, PROBIT, GLM (for General linear models). A more extended statistical discussion and more elaborate statistical analyses are listed at the start of the [SAS/STAT Guide].
