WebWe consider the general situation of testing multiple hypotheses repeatedly in time using recently developed graphical approaches. We focus on closed testing procedures using weighted group sequential Bonferroni tests for the intersection hypotheses. WebSep 1, 2016 · 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 on a Markov-random-field-coupled mixture model. The underlying true states of hypotheses are represented by a latent binary Markov random field, and …
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]
WebDec 2, 2008 · We propose a simple iterative graphical approach to construct and perform such Bonferroni-type tests. 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 … 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 …

The final graph, assuming not all hypotheses were rejected, provides the final Type I error available for testing each hypothesis that was not rejected. imperial jewelers new paltz nyWebgMCP - an R package for a graphical approach to weighted multiple test procedures Kornelius Rohmeyer August 18, 2016.
