Composite Designs Based on Orthogonal Arrays and Definitive Screening Designs
基于正交表与确定性筛选设计的复合设计
Central composite designs are widely used in practice for factor screening and building response surface models. We study two classes of new composite designs. The first class consists of a two-level factorial design and a three-level orthogonal array; the second consists of a two-level factorial and a three-level definitive screening design. We derive bounds of their efficiencies for estimating all and part of the parameters in a second-order model and obtain some general…
