用插入法估计分布函数的水平集:多维扩展

Estimating level sets of a distribution function using a plug-in method: a multidimensional extension

Elena Di Bernadino, Thomas Laloë

摘要:

本文讨论了用$c \in (0,1)$估计未知分布函数$F$在\mathbb{R}^d_+ $. A plug-in approach is followed. That is, given a consistent estimator $ F_n $ of $ F $, we estimate $ L_n(c)$ by $ L_n(c)= \{F_n(x)\geq c \}$上的水平集$L(c)= \{F(x) \geq c \}$.我们状态的一致性结果相对于Hausdorff距离和体积的对称差异。这些结果可以被认为是先前在双变量框架中获得的结果的推广,在Di Bernardino et al.(2011)中。最后,我们调查缩放数据对我们的一致性结果的影响。

英文摘要:

This paper deals with the problem of estimating the level sets $L(c)= \{F(x) \geq c \}$, with $c \in (0,1)$, of an unknown distribution function $F$ on \mathbb{R}^d_+$. A plug-in approach is followed. That is, given a consistent estimator $F_n$ of $F$, we estimate $L(c)$ by $L_n(c)= \{F_n(x) \geq c \}$. We state consistency results with respect to the Hausdorff distance and the volume of the symmetric difference. These results can be considered as generalizations of results previously obtained, in a bivariate framework, in Di Bernardino et al. (2011). Finally we investigate the effects of scaling data on our consistency results.
