二元响应2^2试验最优设计的稳健性

Robustness of Optimal Designs for 2^2 Experiments with Binary Response

Jie Yang, Abhyuday Mandal, Dibyen Majumdar

摘要:

我们考虑一个实验,两个定性因素在2个水平,每个和一个二元响应,遵循广义线性模型。在Mandal,Yang and Majumdar(2010)中,我们得到了特殊情况下局部D-最优设计的基本结果和特征。由于局部最优设计依赖于假设的参数值,因此一个关键问题是设计对这些值的错误指定的敏感性。在本文中,我们研究的灵敏度理论和模拟,并表明最优设计是相当强大的。在一般情况下,我们使用圆柱代数分解的方法来获得局部D-最优设计。

英文摘要:

We consider an experiment with two qualitative factors at 2 levels each and a binary response, that follows a generalized linear model. In Mandal, Yang and Majumdar (2010) we obtained basic results and characterizations of locally D-optimal designs for special cases. As locally optimal designs depend on the assumed parameter values, a critical issue is the sensitivity of the design to misspecification of these values. In this paper we study the sensitivity theoretically and by simulation, and show that the optimal designs are quite robust. We use the method of cylindrical algebraic decomposition to obtain locally D-optimal designs in the general case.
