testPermutation

2 - sample Permutation Test

Function implements 2 - sample permutation non-parametric statistical test. It allows to set parameter alpha;

Function returns multiple information such as pValue, average difference, HypothesisRejection .

function [pValue, avgDif, measDif, h] = testPermutation(data1, data2, permCounts, alpha, initialSeed)

data1 - first group of data (numerical vector)

data2 - second group of data (numerical vector)

permCounts - count of generated permutation in statistical test (positive integer)

alpha - parameter which setting the significant level (default is 0.02)

initialSeed - number which initialize the random number generator, for generating pseudo random permutations. Identical seed is suitable for reaching the same test results.

pValue - p value of statistical test

avgDif - average Difference reached by permutations

measDif - average Difference measured in 2 groups of data

h - statistical test result (1 = we are rejecting H0 hypothesis, 0 = we are not rejecting H0 hypothesis )
