Thanks for your help. But I need to estimator the standard error of the quantile in "survival analysis", because my data is censored. For example~
T<-c(84,240,261,332,348,437,521,565) S<-c(0,1,1,0,1,0,1,0) ##0 for censoed; 1 for event G<-rep(1,8) ori_s.surv<-survfit(Surv(T,S)~G) -- View this message in context: http://r.789695.n4.nabble.com/the-standard-error-of-the-quantile-tp4086479p4086512.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
