Subject: How do i compute predicted failure time from a cox model?
Given a cox model:
?
library(Hmisc); library(survival); (library(Design);
cox.model=cph(Surv(futime,? fustat) ~ age, data=ovarian, surv=T)
str(cox.model)
?
What I need is the total estimated time until failure (death), not the probability of failing at a given time (survival probability), or hazard etc, which is what I get from survest and predict for example.
?
I suspect the answer is embarrassing simple...
