ResumoAbstract Several asymptotic confidence interval methods for U / mn , the Mann–Whitney U statistic divided by the product of the two sample sizes, are developed and evaluated alongside published methods. Novel methods derived from Gaussian and beta models perform well, though overall a modification of the Hanley–McNeil approach (method 5 in this evaluation) performed better and is recommended for calculating confidence intervals for U / mn for continuously distributed data.
