For each subject, the survival function is recomputed leaving that subject out.
This is the workhorse for jackknife.survival2 and will generally not
be called by the user.
Usage
leaveOneOut.survival2(object, times, mr)
Arguments
- object
A survfit object, with a single event (no competing risks)
- times
Times at which the survival is computed, must be length 1
- mr
Model response, the result of a call to Surv, or a matrix with two columns: "time" (observed follow up time) and "status" (0 = censored, 1 = event)
Value
A vector of jackknifed values of survival at time times
Examples
sfit.surv <- survival::survfit(survival::Surv(time, status) ~ 1, data = colon)
mrs <- with(colon, Surv(time, status))
jackvals <- leaveOneOut.survival2(sfit.surv, times = 1000, mrs)
