![]() For example, for arr 1,2,3, the following are. This p-value interval can be used to ensure that the permutation test have both good global power and an acceptable degree of conservatism. A permutation of an array of integers is an arrangement of its members into a sequence or linear order. We propose the p-value interval as a novel measure of the conservatism of a permutation test that can be defined independently of the significance level.

We consider this issue from a variety of perspectives, and conclude that permutation tests are ideal to study efficacy in a randomized clinical trial which compares, in a heterogeneous patient population, two or more treatments, each of which may be most effective in some patients, when the primary analysis does not adjust for covariates. This approach opens the door to broader agreement, but begs the obvious question of when to use permutation tests. A better conclusion might be that there are situations in which permutation tests should be used, and other situations in which permutation tests should not be used. However, because of the conservatism of permutation tests, the virtues of permutation tests continue to be debated in the literature, and conclusions are generally of the type that permutation tests should always be used or permutation tests should never be used. This means that only such design-based permutation tests can ensure internal validity, without which external validity is irrelevant. For randomized clinical trials, permutation tests that reflect the actual randomization are design-based analyses for such hypotheses. Hypothesis testing, in which the null hypothesis specifies no difference between treatment groups, is an important tool in the assessment of new medical interventions. Permutations: A permutation of a set of elements is an ordered arrangement where each element is used once. A signed permutation can be represented in two other ways which may be.
