Permutations in statistics
WebA permutation test involves the shuffling of observed data to determine how unusual an observed outcome is. A typical problem involves testing the hypothesis that two or more samples might belong to the same population. The permutation test proceeds as follows: … Web1. jan 2014 · The proportion of data permutations in the reference set having test statistic values greater than or equal to (or for certain test statistics, less than or equal to) the value for the experimental results is the p-value (significance or probability value). Determining significance on the basis of a distribution of test statistics generated by ...
