In gsoutinho/survrec: Estimation of the multivariate distributions for censored gap times

Description

This function provides survival estimates using the product-limit Kaplan-Meier estimator.

Usage

KM(time, status, t)

Arguments

time	Survival time of the process.
status	Censoring indicator of the survival time of the process; 0 if the survival time is censored and 1 otherwise.
t	The time for obtaining survival estimates.

Examples

require(survival)
data("bladder4state")
obj<- multidf(time1=bladder4state$y1, event1=bladder4state$d1, 
              time=bladder4state$y1+bladder4state$y2,status=bladder4state$d2)
obj2<-obj[[1]]
KM(time = obj2$time, status = obj2$status, t = 20)
fit <- survfit(Surv(obj2$time, obj2$status) ~ 1, data = obj2)
summary(fit, time = 20)$surv
