Main effect plans with an additional search property for 2m factorial experiments

Abstract

This paper presents a new series of main effect plans for 2m factorial experiments which permit search and estimation of one nonnegligible effect from two and three factor interactions. Plans in the series are Balanced Arrays (BA) of strength two. A robustness property of such plans is proved. Main effect plans which are near BA of strength two and with the search property, are obtained from the robustness property. Some other plans are also given. © 1993.
