The CNTSELECT Procedure

The FREQ statement identifies a variable (freq-variable) that contains the frequency of occurrence of each observation. PROC CNTSELECT treats each observation as if it appears n times, where n is the value of freq-variable for the observation. If the value for the observation is not an integer, it is truncated to an integer. If the value is less than 1 or missing, the observation is not used in the model fitting. When the FREQ statement is not specified, each observation is assigned a frequency of 1. For information about combining the FREQ statement with the BAYES statement, see the section Bayesian Analysis with Weighted Likelihoods.
