Permutation Test

A permutation test (aka randomization test) for MATLAB, testing for a difference in means between two samples.

A permutation test (aka randomization test) for MATLAB, testing for a difference in means between two samples. It supports one- and two-tailed tests, and returns a p-value, the observed difference, and the effect size (Hedges' g). The result can optionally be visualized using a histogram. It is also possible to perform exact tests, during which all possible permutations are considered.
