Abstract :In this study a group sequential test of non-parametric statistics is examined in order to compare two groups of survival data. A new general form for a group sequential test of non-parametric statistics is given. The distribution of test statistics, obtained at the end of each stage, have been derived for this general form. In addition, an example based on a simulated data set is used to illustrate the test process that covers the group sequential test of non-parametric statistics in the given general form.Keywords : Group sequential test, Survival data, Log-rank test, Wilcoxon test, TaroneWare family
