For larger n1 and n2, one approach is to … WebJan 1, 2014 · The permutation distribution depends on the observed values, therefore a permutation test is a conditional test, and a huge amount of computing is required. As a result, the Fisher–Pitman permutation test was hardly ever applied before the advent of fast PCs, although it was proposed in the 1930s and its high efficiency was known since …

(Shin Ta Liu, Technometrics, Vol. 44 (3), 2002) WebMar 24, 2024 · The Kruskal-Wallis test and the Fisher-Pitman permutation test can deal with the non-normality, but I believe both require homoscedasticity. Using Welch's ANOVA will help with the unequal variances, but it requires normality. I'm interested in how this community would suggest moving forward with a difference in means analysis.

WebDec 12, 2004 · Here, the Baumgartner-Weiss-Schindler test, a novel and powerful test based on ranks, is investigated and compared with the parametric t-test as well as with two other nonparametric tests (Wilcoxon rank sum test, Fisher-Pitman permutation test) recently recommended for the analysis of gene expression data.
WebIf the smallest sample size is the one with highest variance the test will have inflated Type I error). The Welch-Satterthwaite version of the t-test, on the other hand, does not assume equal variances. If you're thinking of the Fisher-Pitman permutation test, it too assumes equal variances (if you want to infer unequal means from a low p-value).
