Abstract

Two-stage testing procedures are proposed for three statistical problems: one-way analysis of variance and testing the mean of a multivariate normal distribution with first known, and then unknown, covariance matrix. For the first and third problems, a method of obtaining critical values is proposed and evaluated using Monte Carlo simulations. Moreover, for these two problems, two versions of the general F-2 procedure proposed by Chase and Hewett in 1976 are examined. Comparisons between all of the procedures and the corresponding fixed sample size, or one-stage, procedures are made in terms of power and expected sample size. The two-stage procedures proposed here are shown to have power curves that are similar to the one-stage curves while producing lower expected sample size. Thus, the experimenter may use the two-stage procedures to reduce the average sample size without affecting the Type II error.Dept. of Mathematics and Statistics.
