The HPCORR Procedure

The FREQ statement specifies a numeric variable whose value represents the frequency of the observation. If you use the FREQ statement, PROC HPCORR assumes that each observation represents observations, where is the value of the FREQ variable. If is not an integer, SAS truncates it. If is less than 1 or is missing, the observation is excluded from the analysis. The sum of the frequency variables represents the total number of observations.

The effects of the FREQ and WEIGHT statements are similar except when the degrees of freedom are calculated.
