Permutation-based approach
Web"This monograph presents a fresh approach to statistical ideas based on permutation procedures. The focus is not on elaborating a mathematical theory in a theorem-proof framework. Rather it is the authors’ goal to give an overview how permutation methodology may be applied to quite different statistical questions.

WebMar 11, 2024 · To answer question (1) from the introduction, we use a permutation test based approach. We first fit the model and obtain an observed test statistic assessing the quality of the model fit, in our case the observed RMSE. We then permute the competitor species identities and compute a permuted test statistic a large number of times, thereby ...

WebPermutation-based testing approaches are especially important in genomic studies because severe multiple testing conditions require parametric tests to rely exclusively on the extreme tails of the distribution, which are notoriously inaccurate models of real data. Webby permutation of the statistic is not the author’s main interest, but is mentioned in the numerical section. The higher criticism statistic itself is computed based on asymptotic ap-proximations. A similar approach has previously been used in applied settings, for example inSabatti et al.(2009).
