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. http://homepages.math.uic.edu/~rgmartin/Teaching/Stat451/Slides/451notes08.pdf
