FREQ Statement
- FREQ variable < /option > ;
The variable in the FREQ statement identifies a variable
(in the input data set) containing the frequency of occurrence of
each observation.
PROC PHREG treats each observation as if it appears n times,
where n is the value of the FREQ variable for the observation.
If not an integer, the frequency value
is truncated to an integer.
If the frequency value is missing, the observation is
not used in the estimation of the regression parameters.
The following option can be specified in the FREQ statement
after a slash (/):
- NOTRUNCATE
- NOTRUNC
-
specifies that frequency values are not truncated to integers.
