Some inequalities for a LNQD sequence with applications

open access: yesJournal of Inequalities and Applications, 2012
In this paper, some inequalities for a linearly negative quadrant dependent (LNQD) sequence are obtained. As their application, the asymptotic normality of the weight function estimate for a regression function is established, which extends the results ...

Analyzing high dimensional correlated data using feature ranking and classifiers

open access: yesComputational and Mathematical Biophysics, 2019
The Illumina Infinium HumanMethylation27 (Illumina 27K) BeadChip assay is a relatively recent high-throughput technology that allows over 27,000 CpGs to be assayed.

Effect of mean on variance function estimation in nonparametric regression [PDF]

open access: yes, 2008
Variance function estimation in nonparametric regression is considered and the minimax rate of convergence is derived. We are particularly interested in the effect of the unknown mean on the estimation of the variance function. Our results indicate that,

Kink estimation in stochastic regression with dependent errors and predictors [PDF]

open access: yes, 2010
In this article we study the estimation of the location of jump points in the first derivative (referred to as kinks) of a regression function µ in two random design models with different long-range dependent (LRD) structures.

Pac-bayesian bounds for sparse regression estimation with exponential weights [PDF]

open access: yes, 2010
We consider the sparse regression model where the number of parameters $p$ is larger than the sample size $n$. The difficulty when considering high-dimensional problems is to propose estimators achieving a good compromise between statistical and ...

Bias-variance decomposition in Genetic Programming

open access: yesOpen Mathematics, 2016
We study properties of Linear Genetic Programming (LGP) through several regression and classification benchmarks. In each problem, we decompose the results into bias and variance components, and explore the effect of varying certain key parameters on the

Upper bounds and aggregation in bipartite ranking

open access: yes, 2013
One main focus of learning theory is to find optimal rates of convergence. In classification, it is possible to obtain optimal fast rates (faster than n−1/2) in a minimax sense. Moreover, using an aggregation procedure, the algorithms are adaptive to the

Testing the suitability of polynomial models in errors-in-variables problems [PDF]

open access: yes, 2007
A low-degree polynomial model for a response curve is used commonly in practice. It generally incorporates a linear or quadratic function of the covariate.

Uniform in bandwidth consistency of kernel estimators of the density of mixed data

open access: yes, 2015
We establish a general uniform in bandwidth consistency result for kernel estimators of the unconditional and conditional joint density of a distribution, which is defined by a mixed discrete and continuous random variable.
