I’m looking at the Mann-Whitney U test from HypothesisTests.jl , and it is described as follows: Perform a Mann-Whitney U test of the null hypothesis that the probability that an observation drawn from the same population as x is greater than an observation drawn from the same population as y is eq…

Your proposed approach might work in cases with few ties, but it will be downwardly biased in the presence of many ties. For example, you wouldn’t want to conclude that the distributions are different if PR(X>Y) = 0.01, PR(X<Y) = 0.01, and PR(X=Y) = 0.98. When the data are discrete and bounded, a s…
