The table below shows the filename suffices for each of the different test statistics available.

WebThe permutation test can be computationally expensive and not necessarily more accurate than the analytical test, but it does not make strong assumptions about the shape of the underlying distribution. Use of trimming is commonly referred to as the trimmed t-test. WebPerforms a permutation test of a given statistic on provided data. For independent sample statistics, the null hypothesis is that the data are randomly sampled from the same distribution. For paired sample statistics, two null hypothesis can be tested: that the data are paired at random or that the data are assigned to samples at random.
