Notes

This test does not use the standard Wilcoxon Rank-Sum procedure.  Instead, the data are converted to ranks and fed into the two-sample T-Test.  This implementation is described in Rank Transformations as a Bridge Between Parametric and Nonparametric Statistics by W. J. Conover and Ronald L. Iman from The American Statistician, Vol 35, No 3 (Aug., 1981), pp. 124-129.
