Description
Permutational Group Sequential Test for Time-to-Event Data.
Description
Permutational group-sequential tests for time-to-event data based on the log-rank test statistic. Supports exact permutation test when the censoring distributions are equal in the treatment and the control group and approximate imputation-permutation methods when the censoring distributions are different.

permGS
permGS is an R package implementing permutational group-sequential tests for time-to-event data based on the two-sample (weighted) log-rank test statistic. It supports exact permutation test when the censoring distributions are equal in the treatment and the control group and approximate imputation-permutation methods when the censoring distributions are different. One- and two-sided testing is possible.
