Dear all, I write to know if it possible to know the number of censor subject in function of time. I run: os<-survfit(Surv(datios$time,datios$status)) summary(os) but it give me only the nomber of events. Can you help me?
Well, if you know the number of events, you can find the number of censored observations by subtracting the number of events from the number of observations. If you want complete statistics from all risksets (at event times), consider the function 'risksets' in the package 'eha'. G?ran
Thanke you
