Hi Eduardo,

With the stcox postestimation command: "predict s0, basesurv"
I can estimate the baseline survivor function; but how can I get the
SE for the baseline survivor function at each time point?

-survci- is a Stata macro written by Yulia Marchenko that should make available what you are looking for.

I find this command a quite important addition to the official survival commands and I would wish it to be integrated with the estimate of the confidence intervals (and SE) of the covariate-adjusted cumulative hazard.

Best wishes.
