本文研究多响应线性模型中R-最优设计的构造。由Dette(J R Stat Soc Ser B 59:97-110,1997)引入的R-最优性准则使用于参数估计的Bonferroni矩形置信区域的体积最小化。对R-最优性最优设计证明了Elfving定理的一个推广,给出了R-最优设计的一个几何刻画。通过四个例子说明了R-最优设计的几何特征。
The present paper is devoted to the construction ofR-optimal designs in multiresponse linear models. TheR-optimality criterion introduced by Dette (J R Stat Soc Ser B 59:97–110, 1997) minimizes the volume of Bonferroni rectangular confidence region for the parameter estimation. A generalization of Elfving’s theorem is proved for the optimal designs with respect toR-optimality, which gives a geometric characterization ofR-optimal designs. The geometric characterizations of theR-optimal designs are illustrated by four examples.
