Hello jmgreenb, thank you very much for your reply. I understand that p-values are only reported for features when they are significant. However, my question is that when comparing only two classes, “–wilc 0” return no p-value while “–wilc 1” return p-values, when there are significant features. When comparing two classes, K-W and Wilcoxon rank-sum test produces essentially identical results. So I don’t know why when “–wilc 0”, they produce no p-value. They should return p-value from K-W test… And still no input from developers…
I post the other thread regarding this question:
