The UNIVARIATE Procedure

FREQ Statement

FREQ variable ;

The FREQ statement specifies a numeric variable whose value represents the frequency of the observation. If you use the FREQ statement, the procedure assumes that each observation represents $n$ observations, where $n$ is the value of variable. If the variable is not an integer, the SAS System truncates it. If the variable is less than 1 or is missing, the procedure excludes that observation from the analysis. See Example 4.6.

Note: The FREQ statement affects the degrees of freedom, but the WEIGHT statement does not.
