The Performance of One Type Step-Wise Group Screening Designs.

Abstract

In this paper, we evaluate the performance of one type step-wise group screening designs in which group-factors contain equal number of factors in the initial step. We shall examine one type step-wise group screening designs without errors in observations, considering the possibility of cancellation of effects within group-factors. Expressions for the expected total number of runs and the expected number of active factors detected are obtained. The performance of one type step-wise group-screening designs is then compared with the performance of multistage group \ screening designs. Group screening designs have both biological and industrial applications.
