Survival Rate and 95% CI from PROC LIFETEST

davehalltwp — Tue, 23 Jan 2018 15:04:46 GMT

I am trying to calculate a survival rate and corresponding 95% CI from PROC LIFETEST. Is there an ODS data set I can grab that has these?

As I understand it, the survival rate should be the rate at the last observation, right? If so, my survival rate is .0938. But how can I get an 95% CI to go along with that?

Thanks

Try the OUTSURV option on the PROC LIFETEST statement.
