Mean Residual Life

Description

Function to return the mean residual life along with Hall and Wellner's upper and lower bounds.

Usage

mrl(data, alpha, main=NULL, ylim=NULL, xlab=NULL,...)

Arguments

data

a vector of survival times

alpha

(1-alpha) is the approximate coverage probability for the confidence band.

main

title of the plot. The default is "Plot of Mean Residual Life and bounds".

ylim

the limits of the y-axis. The default is to include all points in the plotting range.

xlab

the label for the x-axis. The default is Time.

...

additional plotting options

Value

The function returns a list with three vectors:

PM

the mean residual life

PMU

upper bound for the mean residual life

PML

lower bound for the mean residual life
