WebDec 30, 2014 · Accordingly, a variety of multiple test procedures exist for pharmaceutical trial applications, which are typically defined on a single structured family of null hypotheses. For some confirmatory clinical trials with multiple objectives, however, it is advantageous to address the arising multiplicity problems via grouped families of hypotheses.

Should be either "Bonferroni", "Simes" or "parametric". If not specified by default the Bonferroni-based test procedure is used if no correlation is specified or the algorithm from Bretz et al. 2011 if a correlation is specified. If test is set to "Simes" the weighted Simes test will be performed for each subset of hypotheses. correlation
