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.
