In fastlogranktest: A Fast Way to Calculate the p-Value of One or Multiple Log-Rank-Tests

Description

Calculate the Log-Rank-Test very fast

Usage

logrank_test(groupa, groupb, groupacensored, groupbcensored, onlyz = FALSE)

Arguments

groupa	vector of group a's survival times
groupb	vector of group b's survival times
groupacensored	vector of censored information of group a's survival times
groupbcensored	vector of censored information of group b's survival times
onlyz	(optional) calculate only z-statistic

Value

chi2 statistic, z-statistic, p-value

Examples

T1 <- c(6, 6, 6, 6, 7, 9, 10, 10, 11, 13, 16, 17, 19, 20, 22, 23, 25, 32, 32, 34, 35)
E1 <- c(1, 1, 1, 0, 1, 0, 1, 0, 0, 1, 1, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0)
T2 <- c(1, 1, 2, 2, 3, 4, 4, 5, 5, 8, 8, 8, 8, 11, 11, 12, 12, 15, 17, 22, 23)
