[R] How to get the 5th percentile( with a 95% CI )of the Kaplan-meier estimator?
Hi, all dear R experts, I am really stuck by how to get the 5th percentile( with a 95% CI )of the Kaplan-meier estimator of survival function P(T>t). I have a simulated sample of lifetime Ts, then I set the KM estimator < km.fit<-survfit(Surv(T),type="kaplan-meier",data=Surv(T)) <quantile(km.fit,.05) However, it gave "Error in order...". Does someone have some ideas of how to solve it( with a 95% CI )? Thanks a lot!!!
