rmst: Restricted mean survival time

In nchenderson/DelayedSurvFit: Constrained Survival Estimation with Delayed Treatment

Restricted mean survival time

Description

Computes the restricted mean survival time for both treatment arms.

Usage

rmst(obj, tau0 = NULL, tau1 = NULL)

Arguments

obj	An object of class surv.delay
tau0	Truncation time for control arm
tau1	Truncation time for active treatment arm

Value

A list with the following two components

rmst0	The estimated restricted mean survival time in the control arm
rmst1	The estimated restricted mean survival time in the active treatment arm

Examples

## Not run: 
### Generate simulated survival data
n <- 400
cens.time <- 8
X1 <- rweibull(n, shape=2.3, scale=7)
X2 <- rweibull(n, shape=.8, scale=10)
Y1 <- pmin(X1, cens.time)
Y2 <- pmin(X2, cens.time)
e1 <- as.numeric(X1 < cens.time)
e2 <- as.numeric(X2 < cens.time)

times <- c(Y1, Y2)  ## follow-up times
events <- c(e1, e2) ## event indicators
trt <- rep(c(0,1), each=n)  ## treatment arm assignment

dfs.obj <- DelayedSurvFit(times, events, trt, max.times=50) 
rmst(dfs.obj)

## End(Not run)
