## Abstract For some applications of the WILCOXONβMANNβWHITNEYβstatistic its variance has to be estimated. So e.g. for the test of POTTHOFF (1963) to detect differences in medians of two symmetric distributions as well as for the computation of approximate, confidence bounds for the probability __P

## Abstract For the case of the LEHMANN alternatives the paper presents some new facts on the MANNβWHITNEY statistic and, in particular, its variance __V(p, m, n)__, where __p = P(x__~__i__~<__y__~i~). Explicit formulas for __U__ and __V__ are used to prove, among other things, the following propos
This note is the proof of an important result for the application of random cut-points theory to the Mann-Whitney U test statistic, related directly to the Wilcoxon rank-sum statistic, used when data consist of frequencies in, for example, a 2 Γ k contingency table where the columns correspond to k
