The QLIM Procedure

FREQ Statement

FREQ variable ;

The FREQ statement identifies a variable that contains the frequency of occurrence of each observation. PROC QLIM treats each observation as if it appears $n$ times, where $n$ is the value of the FREQ variable for the observation. If it is not an integer, the frequency value is truncated to an integer. If the frequency 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. If you specify more than one FREQ statement, then the first FREQ statement is used.
