这份报纸考虑感兴趣的效果不得不对一套 nonnegligible 效果直角的试验性的状况。有混合力量的直角的数组的各种各样的类型为在 ANOVA 高尺寸模型表示估计参数是 A 最佳的,这被显示出。包括相互作用的两个盒子在模型被考虑。在里面特别地,所有主要效果的评价在混合力量是 A 最佳的(2, 2 )3 直角的数组和在 G 1 的所有主要效果和二因素的相互作用的评价??
This paper considers experimental situations where the interested effects have to be or- thogonal to a set of nonnegligible effects. It is shown that various types of orthogonal arrays with mixed strength are A-optimal for estimating the parameters in ANOVA high dimension model representation. Both cases including interactions or not are considered in the model. In particularly, the estimations of all main effects are A-optimal in a mixed strength (2, 2)3 orthogonal array and the estimations of all main effects and two-factor interactions in G~ x G~ are A-optimal in a mixed strength (2, 2)4 orthogonal array. The properties are also illustrated through a simulation study.
