WebThe literature distinguishes between two types of permutations tests: (1) the randomization test is the permutation test where exchangeability is satisfied by random assignment of experimental units to conditions; (2) the permutation test is the exact same test but applied to a situation where other assumptions (i.e., other than random … WebFisher's exact test is definitely appropriate when the row totals and column totals are both fixed by design. Some have argued that it may also be used when only one set of margins is truly fixed. This idea arises because the marginal totals n 1 +, n + 1 provide little information about the odds ratio θ. Exact non-null inference for θ
