A permutation test (also called re-randomization test) is an exact statistical hypothesis test making use of the proof by contradiction. A permutation test involves two or more samples. The null hypothesis is that all samples come from the same distribution $${\displaystyle H_{0}:F=G}$$. … Zobraziť viac To illustrate the basic idea of a permutation test, suppose we collect random variables $${\displaystyle X_{A}}$$ and $${\displaystyle X_{B}}$$ for each individual from two groups $${\displaystyle A}$$ Zobraziť viac An important assumption behind a permutation test is that the observations are exchangeable under the null hypothesis. An important consequence of this assumption … Zobraziť viac An asymptotically equivalent permutation test can be created when there are too many possible orderings of the data to allow complete enumeration in a convenient manner. This is done by generating the reference distribution by Monte Carlo sampling Zobraziť viac Permutation tests are a subset of non-parametric statistics. Assuming that our experimental data come from data measured from two treatment groups, the method simply … Zobraziť viac Permutation tests exist for any test statistic, regardless of whether or not its distribution is known. Thus one is always free to choose the statistic which best discriminates between hypothesis and alternative and which minimizes losses.
