Bootstrap hypothesis testing
WebThe permutation test is best for testing hypotheses and bootstrapping is best for estimating confidence intervals. Permutation tests test a specific null hypothesis of exchangeability, i.e. that only the random sampling/randomization explains the difference seen. This is the common case for things like t-tests and ANOVA. WebThe Wilcoxon test needs additional assumptions, however. They are: The random variable of interest is continuous; The probability distribution of the population is symmetric. If we compare the assumptions of the Wilcoxon test to the Sign Test, the Wilcoxon test requires the distribution to be symmetric.
