非参数回归中的核选择

Kernel Selection in Nonparametric Regression

Hélène Halconruy, Nicolas Marie

摘要:

在回归模型$Y = b(X) +σ(X)\varepsilon$中,其中$X$具有密度$f$,本文讨论了$bf$估计的预言不等式,涉及Lerasle等人(2016)意义下的核,通过PCO方法选择。除了Lacour,Massart和Rivoirard(2017)以及Comte和Marie(2020)中已经研究的基于核的估计量的带宽选择之外,还涵盖了$f$和$bf$的各向异性投影估计量的维度选择。

英文摘要:

In the regression model $Y = b(X) +σ(X)\varepsilon$, where $X$ has a density $f$, this paper deals with an oracle inequality for an estimator of $bf$, involving a kernel in the sense of Lerasle et al. (2016), selected via the PCO method. In addition to the bandwidth selection for kernel-based estimators already studied in Lacour, Massart and Rivoirard (2017) and Comte and Marie (2020), the dimension selection for anisotropic projection estimators of $f$ and $bf$ is covered.
