Design admissibility and de la Garza phenomenon in multifactor experiments
多因素实验中的设计可容许性与 de la Garza 现象
The determination of an optimal design for a given regression problem is an intricate optimization problem, especially for models with multivariate predictors. Design admissibility and invariance are main tools to reduce the complexity of the optimization problem and have been successfully applied for models with univariate predictors. In particular, several authors have developed sufficient conditions for the existence of minimally supported designs in univariate models,…
