摘要:

该文给出了球面数据密度函数的核近邻估计,通过对核估计与近邻估计相互关系的讨论,建立了核近邻估计的逐点强相合性及一致强相合性

关键词: 球面数据, 密度函数, 核近邻估计, 逐点强相合性, 一致强相合性

Abstract:

In this article, we introduce a kernel neighbor estimator of density function of spherical data. By investigating the relationship between kernel estimator and kernel neighbor estimator, we establish the strong consistency and the uniformly strong consistency for this kernel neighbor estimator.

Key words: Sphericaldata, Densityfunctionkernelneighborestimator, Pointwisestrongconsistency, Uniformlystrongconsistency
