论文摘要
在统计文献中，对足够的降低方法（SDR）方法以及非线性扩展引起了很多兴趣。在本说明中，我们使用有关度量空间和正定函数的经典结果将线性SDR程序与其非线性对应物联系起来。
There has been a lot of interest in sufficient dimension reduction (SDR) methodologies as well as nonlinear extensions in the statistics literature. In this note, we use classical results regarding metric spaces and positive definite functions to link linear SDR procedures to their nonlinear counterparts.
