We propose a multiple testing procedure which is based on a Markov-random-field-coupled mixture model. The underlying true states of hypotheses are represented by a latent binary Markov random field, and …

Graphical approaches for the control of generalized error rates

WebThe graphical testing produces a sequence including the original multiplicity graph, followed by updated multiplicity graphs, each with a single hypothesis rejected from the previous graph. The final graph, assuming not all hypotheses were rejected, provides the final Type I error available for testing each hypothesis that was not rejected. WebLarge-scale multiple testing tasks often exhibit dependence. Leveraging the dependence between individual tests is still one challenging and important problem in statistics. With recent advances in graphical models, it is feasible to use them to capture the dependence among multiple hypotheses.

WebMar 1, 2024 · A Graphical approach was proposed to test multiple hypotheses based on Bonferroni test, and it was extended to more graphical test procedures using weighted Simes test or parametric test [5, 6]. Graphical approaches provide visualized and powerful multiple testing procedures to control familywise Type I error, and also facilitate the ... If m independent comparisons are performed, the family-wise error rate (FWER), is given by Hence, unless the tests are perfectly positively dependent (i.e., identical), increases as the number of comparisons increases. If we do not assume that the comparisons are independent, then we can still say: which follows from Boole's inequality.
