On the distribution of the maximum of the longrank statistic and the modified Wilcoxon statistic

The asymptotic distribution of the maximum of the logrank statistic and the modified Wilcoxon statistic is examined [in order to test] the equality of two survival distributions. A table is provided to facilitate use of the maximum statistics and Monte Carlo simulation experiments are used to investigate the small-sample properties of the maximum statistic. An example is given to illustrate the use of the methods developed in this paper. (SUMMARY IN FRE) (EXCERPT)
