The situation where k populations are partitioned into one inferior group and one superior group is considered. The statistical problem is to select a random size subset of superior populations while trying to avoid including any inferior populations. A selection procedure is assumed to satisfy the condition that the probability of selecting at least one superior population is bounded below by P1<1. The performance of a procedure is measured by the probability of including an inferior population.The asymptotic performance, as k→∞ of Gupta's traditional maximum type procedure ψG is considered in the location-model. For normally distributed populations, ψG turns out to be asymptotically optimal, provided the size of the inferior group does not become infinitely larger than the size of the superior group. 相似文献
