A permutation test (also called re-randomization test or shuffle test) is an exact statistical hypothesis test. A permutation test involves two or more samples.

Nov 14, 2025 · What Is a Permutation Test? A permutation test is a statistical hypothesis test that evaluates whether observed differences between groups are likely to be real or simply the …

Sep 21, 2021 · Permutation tests are non-parametric tests that require very few assumptions. So, when you don’t know much about your data generating mechanism (the population), …

Fisher’s exact test statistic, rank sum test statistic, etc. Any statistic gives a valid and exact p-value but power may differ Could use regression models or machine learning algorithms.

May 15, 2025 · Guide to permutation tests in nonparametric statistics, covering underlying principles, step-by-step implementation, and interpreting test results.

Like bootstrapping, a permutation test builds - rather than assumes - sampling distribution (called the “permutation distribution”) by resampling the observed data.
