COMPUTATION OF THE E(s2) VALUES OF SOME E(s2) OPTIMAL SUPERSATURATED DESIGNS

A supersaturated design is a design whose run size is not enough for estimating all the main effects represented by the columns of the design matrix.It is widely used in the preliminary stages of industrial statistics and other scientific experiments.In this paper,formulas for computing the E(s2) values of E(s2) optimal supersaturated designs with m=t(n－1) ± e(e = 1 and 2) are given,and the accuracy and convenience of using these formulas are demonstrated by an example.
