Estimating survival?
Apologies, I located the function in cph (... time.inc =30, surv = TRUE) ... $surv.summary Thanks. Min-Han

Hi, Sorry to trouble the list. I have a problem which I'm not sure how to resolve. I have a Cox model with 1 independent variable with 2 categories (and thus 2 survival curves on plotting survfit) How can I get an estimate of survival for each category at a particular time point, with standard error? Looking through ?cph and ?coxph, I'm not quite sure how to go about that. I would really appreciate any direction here. Thanks a million! Min-Han
