On the Lehmann Power Analysis for the Wilcoxon Rank Sum Test
Abstract
The Wilcoxon Rank Sum (or Mann-Whitney) Test is among the most useful and powerful of the non-parametric hypothesis tests. However, as with many hypothesis tests, when a clear alternative hypothesis and corresponding power analysis is not present, the practical interpretation of results using this test suffers greatly. This paper presents and clarifies an alternative suggested by E. L. Lehmann in 1953 and provides tables of practical use which have not previously been calculated due to computational difficulties.
