Hi! How to compute probabilities of survival from rpart object? Consider the following example: library(rpart) survtree <- rpart(Surv(time,status)~., data=aml) This code will produce the following survival tree: 1) root 23 26.44184 1.0000000 2) x=Maintained 11 12.61182 0.6848303 * 3) x=Nonmaintained 12 10.81338 1.4426070 * If I am not wrong the rightmost numbers are relative risks compared to whole population (e.g. root node). How to get survival probability function S(t|x)? Regards, Ludvik
