Estimates survival using KaplanMeier estimation
Description
Estimates the probability of survival past some specified time using KaplanMeier estimation
Usage
surv.km.base(tl, dl, tt, weight.perturb = NULL)
Arguments
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.

Value
estimate of survival at the specified time
