proc lifereg data=Headache;
class Group;
model Minutes*Censor(1)=Group/Dist=Weibull;
run;

 

proc phreg data=Headache;

class group;

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?

How about for proc PHREG predictive probability.

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?
