Graphical approach multiple testing
WebJ-STAGE Home 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. We propose a multiple testing procedure which is based …

Tian … 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 ...
WebMultiple comparisons arise when a statistical analysis involves multiple simultaneous statistical tests, each of which has a potential to produce a "discovery." A stated confidence level generally applies only to each test considered individually, but often it is desirable to have a confidence level for the whole family of simultaneous tests.[4] WebFeb 15, 2009 · The resulting multiple test procedures are represented by directed, weighted graphs, where each node corresponds to an elementary hypothesis, together with a simple algorithm to generate such graphs while sequentially testing the individual hypotheses. The approach is illustrated with the visualization of several common …
WebThe graphical approach of Bretz et al (2009) is a flexible and easily communicable way of controlling the FWER while respecting complex trial objectives and multiple structured hypotheses. However, the FWER can be a very stringent criterion that leads to procedures with low power, and may not be appropriate in exploratory trial settings.
