Permutation-based true discovery guarantee by sum tests

WebPermutation-based probabilities are calculated as the proportion of permutations in which the computed value of the test statistic is equal to or more extreme than the actual value. … Web24. júl 2024 · 1.2 Permutation Test. Normal-based statistics are often used in statistical hypothesis testing, which, however, requires either normally distributed data or a large sample size. Moreover, independent observations are assumed. In other words, given the level of predictors, the observations on the outcome variable should be independent of … farcys

WebPermutation test又称randomization test，是Fisher[1]和 Pitman[2]等人于20世纪30年代提出的一种统计推断的方法，其属于一种非参数检验，对样本总体分布情况无要求，特别适 … http://web.mit.edu/r/current/arch/i386_linux26/lib/R/library/multtest/html/mt.maxT.html 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 is that tests of difference in location (like a permutation t-test) require equal … Zobraziť viac • Permutational analysis of variance Zobraziť viac Original references: • Fisher, R.A.
