NettetIn this paper, we consider multiplicity testing approaches mainly for phase 3 trials with two doses. We review a few available approaches and propose some new ones. ... We review the Hochberg procedure, the Bonferroni procedure, and a few consistency-adjusted procedures, ... NettetHommel procedures (Hommel, 1988,?). The Hochberg procedure was derived using a direct argument without an explicit reference to the closure principle and has a simple stepwise structure. The Hommel procedure was deﬁned as a closed testing procedure by specifying tests for all intersection hypotheses in the closed family. This procedure …

NettetMultiplicity in clinical trials may appear under several different guises: multiple endpoints, multiple treatment arm comparisons, and multiple looks at the data during interim … Nettet28. mai 2008 · In carrying out this decision we face a massive multiplicity problem. In the context of high throughput gene expression data, several procedures have been proposed to address such decision problems on the basis of the notion of false discovery rates (Benjamini and Hochberg, 1995; Storey, 2002). fred armisen biography
