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

Description

Calculate multiple Log-Rank-Tests very fast

Usage

multi_logrank_test(
  groupas,
  groupbs,
  groupacensoreds,
  groupbcensoreds,
  threadnumber = NULL,
  onlyz = FALSE
)

Arguments

groupas	list of vectors of groupa's survival times
groupbs	list of vectors of groupb's survival times
groupacensoreds	list of vectors of censored information of groupa's survival times
groupbcensoreds	list of vectors of censored information of groupb's survival times
threadnumber	(optional) set the number of threads used for this function
onlyz	(optional) calculate only z-statistic

Value

vector of chi2 statistic, z-statistic, p-value (same order as input)
