Baseline survival estimate
...not the baseline survival estimate. Is there a way to obtain the baseline survival estimate or do I have to use the formula which does something like S(t) = exp[- the integral from 0 to t of h(u) du]? Thank you for your assistance, Laura fit1 <- coxph(Surv(tsecond/365,seccens)~stroke(smess1)+othnd(smess1)+relat(smess1)+asleep(smess1)+abeeg1(smess1)+treat(smess1),data=smess1) basehaz(fit1) where stroke is a function which creates a binary variable from the dataset smess1 etc. [[alternative HTML version deleted]]
