Abstract
We consider pairwise multiple comparison in k normal populations with unequal variances. Games and Howell (1976) proposed a single-step multiple comparison test based on two-sample test statistics of Welch (1949). We propose a closed testing procedure for pairwise multiple comparison. By computational simulations of the power, it is shown that the closed testing procedure is superior to the single-step multiple comparison test procedure of Games and Howell (1976).
