The FREQ Procedure

Syntax: FREQ Procedure

The following statements are available in PROC FREQ:

PROC FREQ <options> ;
BY variables ;
EXACT statistic-options </ computation-options> ;
OUTPUT <OUT=SAS-data-set> options ;
TABLES requests </ options> ;

The rest of this section gives detailed syntax information for the BY, EXACT, OUTPUT, TABLES, TEST, and WEIGHT statements in alphabetical order after the description of the PROC FREQ statement. Table 3.3 summarizes the basic function of each PROC FREQ statement.
