The test is more sensitive to differences in median survival times than to differences in shape of the survival curves. The asymptotic distribution of the test statistic is derived under both the null and the alternative hypotheses and its variance is shown to take a simple form. sand cloud earthWebRON BROOKMEYER and JOHN CROWLEY* A k-sample median test for censored data is proposed.
