How can I obtain survival estimates from PROC SURVEYPHREG?


PROC SURVEYPHREG cannot be used to produce survival estimates. The BASELINE and OUTPUT statements, typical of PROC PHREG, are not available in PROC SURVEYPHREG.

If the objective is to compute the estimated survival function then PROC PHREG with the WEIGHT statement can be used. However, if the standard errors of the estimated survival are required then PROC PHREG should not be used. The point estimates from PROC PHREG will be correct for a survey setting, however the standard errors will not.
