Comparison of Mixture Designs Obtained Through Projections

摘要

Box and Hau [4] and Prescott [18] discussed projection designs for mixture experiments. In this paper, we consider the projections of four types of standard three - level designs into the mixture simplex and provide efficiency measures for the resulting mixture designs when Scheffe's quadratic model and Darroch's quadratic models are fitted. We also tabulate and compare the uniformity measures for these designs.
