Dear list, I'm trying to understand what kind of uncertainty intervals are plotted for survival::survfit.coxph when 'conf.int=TRUE' is called, e.g.:
f <- coxph(Surv(futime, fustat) ~ age, data = ovarian) s <- survfit(f, newdata=data.frame(age=c(30, 60))) plot(s, conf.int=TRUE) Are these bands the confidence intervals for the survivor function or prediction intervals? Is it possible to get prediction intervals?
