Permutation and Randomization Tests1 ...
0:012 for a single test but p = 0:075 for the permutation test. The theoretical distribution for the maximum has the right range but the permutation distribution is quite discrete. The discreteness is more serious with small sample size and rare SNPs. [The theoretical distribution is not easy to compute except when the tests are independent.] 5.24 How can I implement a permutation test on this data to test the significance of a correlation between the area of lake and richness of a species? Permutation tests for comparing two populations could be widely used in practice because of flexibility of the test statistic and minimal assumptions. The Wilcoxon sum rank test is more powerful than a t test statistic for moderate and large sample sizes for heavier tailed distributions. Using a Resampling Stats,[…]
