rrml: Restricted residual mean life

In nchenderson/DelayedSurvFit: Constrained Survival Estimation with Delayed Treatment

Restricted residual mean life

Description

Computes the restricted residual mean life for both treatment arms.

Usage

rrml(obj, t0, t1, tau0 = NULL, tau1 = NULL)

Arguments

obj	An object of class surv.delay
t0	The lower trunctation time in the control arm.
t1	The lower trunctation time in the active treatment arm.
tau0	The upper trunctation time in the control arm.
tau1	The upper trunctation time in the active treatment arm.

Value

A list with the following two components

rrml0	The restricted residual mean life in the control arm
rrml1	The restricted residual mean life 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) 
rrml(dfs.obj, t0=3, t1=3)

## End(Not run)
