The HPBIN Procedure

The variable in the FREQ statement identifies a numeric variable in the data set that contains the frequency of occurrence for each observation. The HPBIN procedure treats each observation as if it appeared n times, where n is the value of the variable for the observation. If n is not an integer, it is truncated to an integer. If n is less than 1 or is missing, the observation is not used in the analysis. When the FREQ statement is not specified, each observation is assigned a frequency of 1.
