The authors describe a technique for comparing the survival functions of quality adjusted lifetime from 2 treatments. When quality adjusted lifetime is the same as the survival time, the test statistic becomes the ordinary log-rank test. To examine the behavior of the proposed test statistic under null and alternative hypotheses, simulation experiments are performed.
