GROUP SEQUENTIAL TEST OF NON-PARAMETRIC STATISTICS FOR SURVIVAL DATA
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.
