Large Sample Optimality of Least Squares Cross-Validation in Density Estimation
TLDR
This article showed that least square cross-validation is asymptotically optimal for density estimation, rather then simply consistent, in the sense that the tail conditions are only slightly more severe than the hypothesis of finite variance.Abstract:
We prove that the method of cross-validation suggested by A. W. Bowman and M. Rudemo achieves its goal of minimising integrated square error, in an asymptotic sense. The tail conditions we impose are only slightly more severe than the hypothesis of finite variance, and so least squares cross-validation does not exhibit the pathological behaviour which has been observed for Kullback-Leibler cross-validation. This is apparently the first time that a cross-validatory procedure for density estimation has been shown to be asymptotically optimal, rather then simply consistent.read more

TL;DR: In this paper, a survey on the model selection performances of cross-validation procedures is presented, with a particular emphasis on distinguishing empirical statements from rigorous theoretical results, and guidelines are provided for choosing the best crossvalidation procedure according to the particular features of the problem in hand.

An alternative method of cross-validation for the smoothing of density estimates
TL;DR: An alternative method of cross-validation, based on integrated squared error, recently also proposed by Rudemo (1982), is derived, and Hall (1983) has established the consistency and asymptotic optimality of the new method.

Risk bounds for model selection via penalization
TL;DR: It is shown that the quadratic risk of the minimum penalized empirical contrast estimator is bounded by an index of the accuracy of the sieve, which quantifies the trade-off among the candidate models between the approximation error and parameter dimension relative to sample size.

Bandwidth Choice for Nonparametric Regression
TL;DR: In this article, the problem of choosing a bandwidth parameter for nonparametric regression is studied and the relationship of this estimate to a kernel estimate is discussed, based on an unbiased estimate of mean square error, which is shown to be asymptotically optimal.

Weak and Strong Uniform Consistency of the Kernel Estimate of a Density and its Derivatives
TL;DR: In this article, the estimation of a density and its derivatives by the kernel method is considered, and uniform consistency properties over the whole real line are studied under certain conditions on the density and on the behavior of the window width which are necessary and sufficient for weak and strong uniform consistency of the estimate of the density derivatives.
