WebMay 31, 2024 · I'm trying to run a same permutation test for the null hypothesis of no difference between means with the coin and resample R packages. However, I get quite different p-values, which I was not expecting. ... $\begingroup$ one problem is that coin uses Fisher-Pitman permutation test which does not test the difference between means. … WebDec 19, 2024 · From what I understood, the test statistic is computed for each possible permutation of all my observations in order to get an empirical probability density …
WebQuantitative data from the luciferase assays on COS7 cells were explored using one-way ANOVA followed by a nonparametric permutation test, the K-Sample Fisher–Pitman Permutation Test. WebThe Fisher-Pitman permutation test is so-named because we look at all possible permutations of the signs of the differences. If under the null hypothesis these signs are due to random assignment to conditions, we …

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). polygraphic cipherA permutation test (also called re-randomization test) is an exact statistical hypothesis test making use of the proof by contradiction.
