Estimate Weibull Parameters for Survival Data

CamdenShawn — Wed, 19 Feb 2020 17:18:29 GMT

If I just have time-to-event measurements and all I want to do is estimate the parameters for the 2-parameter Weibull, how would I do that in SAS? Is there a built in program or do I need to code a program that goes through MLE estimation for each parameter?

It sounds like you want to use PROC PHREG to fit a two-parameter Weibull model.

See the Getting Started example for PROC PHREG. as well as other examples in the doc

proc lifereg data=Have; 
model y = x / dist = Weibull;
run;
