Thank you for the response. I've explored the output function, too. My baseline statement is as follows:           baseline out = dataset survival = surv; After looking at my output dataset, it appears that each covariate's values are mean values -- which isn't what I expected. Is this something I should be concerned with?  With the survival function estimate by length of observation, I could go back in my original data set and merge in my estimates with observations that accumulate that length of observation, correct?  I think I was thrown by expecting to see in my output dataset each patient identifier with respective 1's and 0's according to their covariate value and a survival estimate at the end.  What's going on with the mean covariate values in the output dataset? Do you know anything about that? Again, thank you for your responses. ... View more

Thank you for your suggestion. From what I understand, the outsurv statement accompanies PROC LIFETEST, not PHREG. I need to obtain the probability of death, adjusted by covariates from my dataset. With the BASELINE statement for PHREG I have tried the SURVIVAL = _ALL_ option but my output appeared to be each covariate's mean by days of observation with survival function estimates, standard error and upper and lower confidence bounds for the survival estimate. ...
