The following table is built in the requested Output Database by the Mann-Whitney/Kruskal-Wallis test analysis. Group By Variables, if present, is the Unique Primary Index (UPI). Otherwise, Z is the UPI. In the case of Mann-Whitney/Kruskal-Wallis Independent Tests, the additional column _twm_independent_variable contains the column-name of the independent variable for each separate test.
