STANDARD Procedure

FREQ Statement

Specifies a numeric variable whose values represent the frequency of the observation.

Tip:	The effects of the FREQ and WEIGHT statements are similar except when calculating degrees of freedom.
See:	For an example that uses the FREQ statement, see FREQ

FREQ variable;

variable: 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 n is not an integer, the SAS System truncates it. If n is less than 1 or is missing, the procedure does not use that observation to calculate statistics but the observation is still standardized.

The sum of the frequency variable represents the total number of observations.
