Wilcoxon rank sum test
This test returns the p-value of a two-sided Wilcoxon rank sum test. This tests the null hypothesis that data in x and y are samples from continuous distributions with equal medians, against the alternative that they are not.
The test assumes that the two samples are independent. x and y can have different lengths.
double []x; // dataset 1
double []y; // dataset 2
double alpha = 0.05; // Significance level scalar value in the range 0 to 1
// get the info for x and y arrays
double p = new SignRank(x, y, alpha).getP()mvn package
