密度可能不存在时的核估计

研究问题
当分布含质量点、非光滑部分或奇异成分,通常意义的密度可能不存在时,如何统一描述核密度与条件均值估计的渐近行为?
方法与思路
作者借助广义函数与广义随机过程,在广义意义下定义任意分布的密度及导数,并分析核密度和 Nadaraya–Watson 条件均值估计。
材料陈述的贡献
摘要称建立涵盖奇异分布成分的统一理论,以广义高斯过程完整刻画核密度估计的极限过程,并给出条件均值估计的渐近结果。
阅读关注点
应核对广义函数空间与收敛方式、各类分布成分的处理、核与带宽条件,以及广义过程结果如何转化为实际可解释的估计结论。
阅读边界
仅据所给 Crossref 摘要,不能将广义密度解释为普通点态密度;摘要未说明常规置信区间、具体速率或实际实现方式。

原文摘要

Nonparametric kernel estimation of density and conditional mean is widely used, but many of the pointwise and global asymptotic results for the estimators are not available unless the density is continuous and appropriately smooth; in kernel estimation for discrete-continuous cases smoothness is required for the continuous variables. Nonsmooth density and mass points in distributions arise in various situations that are examined in empirical studies; some examples and explanations are discussed in the paper. Generally, any distribution function consists of absolutely continuous, discrete, and singular components, but only a few special cases of nonparametric estimation involving singularity have been examined in the literature, and asymptotic theory under the general setup has not been developed. In this paper the asymptotic process for the kernel estimator is examined by means of the generalized functions and generalized random processes approach; it provides a unified theory because density and its derivatives can be defined as generalized functions for any distribution, including cases with singular components. The limit process for the kernel estimator of density is fully characterized in terms of a generalized Gaussian process. Asymptotic results for the Nadaraya–Watson conditional mean estimator are also provided.
