FREQ variable;
The variable in the FREQ statement identifies a numeric variable (in the input data set) that contains the frequency of occurrence for each observation. PROC BGLIMM treats each observation as if it appears f times, where f is the value of the FREQ variable for the observation.
The following option can be specified in the FREQ statement after a slash (/):
By default, the frequency value is truncated to an integer if it is not an integer. If the frequency value is less than 1 or missing, the observation is not used in the analysis. When the FREQ statement is not specified, each observation is assigned a frequency of 1.
