  "Description": "Performs the permutation test using difference in the\nrestricted mean survival time (RMST) between groups as a\nsummary measure of the survival time distribution. When the\nsample size is less than 50 per group, it has been shown that\nthere is non-negligible inflation of the type I error rate in\nthe commonly used asymptotic test for the RMST comparison.\nGenerally, permutation tests can be useful in such a situation.\nHowever, when we apply the permutation test for the RMST\ncomparison, particularly in small sample situations, there are\nsome cases where the survival function in either group cannot\nbe defined due to censoring in the permutation process.\nHoriguchi and Uno (2020) <doi:10.1002/sim.8565> have examined\nsix workable solutions to handle this numerical issue. It\nperforms permutation tests with implementation of the six\nmethods outlined in the paper when the numerical issue arises\nduring the permutation process. The result of the asymptotic\ntest is also provided for a reference.",
