These test methods are considered more effective than log-rank and Wilcoxon tests when the survival curves are not proportional. In this article we use a classification function in the objective is to probability the median parameter, this method makes it possible to determine an interval with different probabilistic weights and simplifies the comparison between the survival functions.
