In this study we discuss stepwise multiple comparison procedures for normal variances intended to obtain higher power compared to the single step procedures proposed by Imada (2018A, 2018B). Specifically, we construct the sequentially rejective step down procedure and the step up procedure for the multiple comparison with a control. Furthermore, we construct the closed testing procedure called Ryan-Einot-Gabriel-Welsch’s procedure for the all-pairwise multiple comparison. Finally, we give some numerical results regarding critical values and power of the test intended to compare the procedures. |
