Fisher pitman permutation test
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). WebThis article investigates the theoretical and empirical performance of Fisher-Pitman-type permutation tests for assessing the equality of unknown Poisson mixture distributions. …

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. WebOct 13, 2024 · We performed a two-sample Fisher-Pitman permutation test (10,000 permutations) using the coin package to compare differences in current and future threats between hotspots and nonhotspot regions. We adjusted P values using the method holm to account for multiple comparisons.

WebThe Fisher-Pitman permutation test can detect any type of difference between two samples: hence, a significant Fisher-Pitman permutation test does not necessarily … 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 …
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 function. In my case, the number of permutations is ( 2 + 6)! = 40320. So the lowest p-value that can be calculated is equal to 1 / 8!, wich is around 2 ⋅ 10 − 5.
