Implemented are the one-sided and two-sided
multiple-direction logrank test for two-sample right
censored data. In addition to the statistics p-values are calculated:
1. For the one-sided testing problem one p-value based on a
wild bootstrap approach is determined. 2. In the two-sided case
one p-value based on a chi-squared approximation and
a second p-values based on a permutation approach are calculated.
