标题： Identifying locally optimal designs for nonlinear models: A simple extension with profound consequences

摘要： 我们扩展了[《Ann. Statist.》2010年第38卷第2499-2524页]中关于非线性模型局部最优设计的方法。从概念上讲，这种扩展相对简单，但在应用方面却有着深远的影响。正如我们将展示的那样，我们可以得到许多最优准则下的局部最优设计结果，以及比以往研究范围更广的一类模型的结果。在许多情况下，这些结果会导致具有最少支撑点的最优设计。 显示英文摘要

摘要： We extend the approach in [Ann. Statist. 38 (2010) 2499-2524] for identifying locally optimal designs for nonlinear models. Conceptually the extension is relatively simple, but the consequences in terms of applications are profound. As we will demonstrate, we can obtain results for locally optimal designs under many optimality criteria and for a larger class of models than has been done hitherto. In many cases the results lead to optimal designs with the minimal number of support points.
