WebAs such, it controls the family-wise error rate for all the k hypotheses at level α in the strong sense. Multiple test procedures developed using the graphical approach for constructing and illustrating multiple test procedures [2] are a subclass of closed testing procedures. See also [ edit] Multiple comparisons Holm–Bonferroni method 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]

Multiple 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.

WebThe authors gave examples in the context of testing two hierarchically ordered endpoints in two-armed group sequential trials with one interim analysis. We consider the general situation of testing multiple hypotheses repeatedly in time using recently developed graphical approaches. Websimple 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 individual hypotheses.
