proc lifereg data=Headache;

model Minutes*Censor(1)=Group/Dist=Weibull;

proc phreg data=Headache;

model Minutes*Censor(1)=Group;
run;

What do I need to do to have the predictive survival probability ?

Have you tried adding an OUTPUT statement?

Example

How about for proc PHREG predictive probability.

Same thing, did you try that?

I can get the predictive probability using proc lifereg . Now my question is how about for phreg procedure

Did you try adding an OUTPUT statement as well to your PROC PHREG?
