FREQ Statement
-
FREQ variable;
If one variable in your data set represents the frequency of occurrence for the other values in the observation, specify the
variable’s name in a FREQ statement. PROC CALIS then treats the data set as if each observation appears 
times, where is the value of the FREQ variable for observation i. Only the integer portion of the value is used. If the value of the FREQ variable is less than 1 or is missing, that observation
is not included in the analysis. The total number of observations is considered to be the sum of the FREQ values. You can
use only one FREQ statement within the scope of each GROUP
or the PROC CALIS statement.
