Survival Rate and 95% CI from PROC LIFETEST

[davehalltwp]

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.
