Graphical approaches to multiple testing
WebMany multiple testing procedures (MTP) have been developed in recent years. Among these new procedures, the graphical approach is flexible and easy to communicate with non-statisticians. A hypothetical Phase III … 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.
