WebJan 18, 2024 · In this section, we introduce the core graphical approach, which can be usedto construct new and extend existing multiple test procedures. More specif-ically, we describe the graphical approach to Bonferroni-based sequentiallyrejective multiple test procedures from Bretz et al. (2009). 14.3.1 Bonferroni-Based Graphical Test Procedures WebJan 1, 2024 · The graphical approach is a framework used to construct and perform Bonferroni-based sequential testing procedures, while achieving strong control of the FWER based on the closed testing principle [12, 18]. Bretz et al. [19] provided an in-depth overview of the graphical approach. The approach has the advantage of being intuitive and flexible.
