twosamplesurvpvs {MultNonParam}

Two Sample Omnibus Tests of Survival Curves

Description

Returns the Kolmogorov-Smirnov and Anderson-Darling test statistics for two right-censored data sets.

Usage

twosamplesurvpvs(times, delta, grp, nmc = 10000, plotme = TRUE, exact = FALSE)

Arguments

times

Event and censoring times

delta

Indicator of event (1) or censoring (0).

grp

Variable that divides the population into groups.

nmc

Number of Monte Carlo samples for p value calculation

plotme

logical; indicates whether to plot or not.

exact

logical; indicates whether to use exhaustive enumeration of permutations or not.

Details

The function calls a Fortran code to calculate the estimators b and their variance-covariance matrix Vb

Value

A vector of length two, with the Kolmogorov-Smirnov and Anderson-Darling statistics.

Examples
