Dear all,
Does any one know how to calculate the risk (death rate) at some
time point (say 5 yrs) based on Kaplan-Meier curve in coxph model in
R? I know how to fit the survival data with coxph. But need to
calculate risk at some time point. Many thanks.
Have you looked at either:
?survfit.coxph
?predict.coxph # with type ="expected"
This seems to be a particularly common question this week. Is there
some sort of class project that is due before the holidays?
