WebOne very typical use of hierarchical testing is for noninferiority studies. For example, if the study shows the experimental arm to be noninferior to the standard of care arm, then superiority may be tested with p-value of 0.05. If the first test is negative, the second test cannot be performed. This is intuitive for the noninferiority.
