R Documentation

Estimates survival using Kaplan-Meier estimation

Estimates the probability of survival past some specified time using Kaplan-Meier estimation

surv.km.base(tl, dl, tt, weight.perturb = NULL)

`tl`	observed event time of primary outcome, equal to min(T, C) where T is the event time and C is the censoring time.
`dl`	event indicator, equal to I(T<C) where T is the event time and C is the censoring time.
`tt`	the time of interest, function estimates the probability of survival past this time
`weight.perturb`	an optional weight matrix to be incorporated in estimation.
