chisq.loglog: Compares Three or More Survival Estimates Using Complementary Log-log Test

Description

This is an internal function and is not usually called by user. This function computes chi-square test for the comparison of three or more survival curves at fixed points in time using complementary log-log transformation of the survival estimates.

Usage

chisq.loglog(st, ot.sq)

Arguments

st

point estimates at fixed points in time

ot.sq

estimated variance

Value

chi-square test statistic
