WebSeveral reproducibility probability (RP)-estimators for the binomial, sign, Wilcoxon signed rank and Kendall tests are studied. Their behavior in terms of MSE is investigated, as well as their performances for RP-testing. Two classes of estimators are considered: the semi-parametric one, where RP-estimators are derived from the expression of the exact or … Web15 de mar. de 2024 · I want to compute a ranksum test statistic for a small sample (n=32). scipy.stats.mannwhitneyu uses a normal approximation for the test statistic and the associated p-value (see here).For small samples, this might be misleading.
