SUPERSATURATED DESIGN WITH MORE THAN TWO LEVELS

Supersaturated designs are useful in screening experiments. This paper discusses the topic or multi-level supersaturated design. Two quantities, E(d²) and D_f, are proposed to evaluate the optimality of supersaturated designs. A lower bound of E(d²) is obtained with a necessary condition for achieving it. Some E(d²)-optimal supersaturated designs of 3, 4, and 5 levels are given.
