WebOct 13, 2024 · We performed a two-sample Fisher-Pitman permutation test (10,000 permutations) using the coin package to compare differences in current and future threats between hotspots and nonhotspot regions. We adjusted P values using the method holm to account for multiple comparisons. WebFeb 1, 2004 · The Fisher-Pitman permutation test can detect any type of difference between two samples; hence, a significant Fisher-Pitman permutation test does not necessarily provide evidence for a difference in means. It is possible, however, to test separately for differences in means and variances.
