Baseline survival estimate
...tion and 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.
