Robust Estimation and Wavelet Thresholding in Partial Linear Models [PDF]

open access: yes, 2006
This paper is concerned with a semiparametric partially linear regression model with unknown regression coefficients, an unknown nonparametric function for the non-linear component, and unobservable Gaussian distributed random errors.

Model selection for regression on a random design [PDF]

open access: yesESAIM: Probability and Statistics, 2002
Summary: We consider the problem of estimating an unknown regression function when the design is random with values in \(\mathbb{R}^k\). Our estimation procedure is based on model selection and does not rely on any prior information on the target function.

A Simple Class of Bayesian Nonparametric Autoregression Models [PDF]

open access: yes, 2013
We introduce a model for a time series of continuous outcomes, that can be expressed as fully nonparametric regression or density regression on lagged terms.

Goodness of Fit Tests in Random Coefficient Regression Models [PDF]

open access: yesAnnals of the Institute of Statistical Mathematics, 1999
Random coefficient regressions have been applied in a wide range of fields, from biology to economics, and constitute a common frame for several important statistical models. A nonparametric approach to inference in random coefficient models was initiated by Beran and Hall.

Random model trees: an effective and scalable regression method [PDF]

open access: yes, 2010
We present and investigate ensembles of randomized model trees as a novel regression method. Such ensembles combine the scalability of tree-based methods with predictive performance rivaling the state of the art in numeric prediction.

The consistency of estimator under fixed design regression model with NQD errors

open access: yes, 2013
In this article, basing on NQD samples, we investigate the fixed design nonparametric regression model, where the errors are pairwise NQD random errors, with fixed design points, and an unknown function.

Linearization of randomly weighted empiricals under long range dependence with application to nonlinear regression quantiles [PDF]

open access: yes, 2000
This paper discusses some asymptotic uniform linearity results of randomly weighted empirical processes based on long range dependent random variables+ These results are subsequently used to linearize nonlinear regression quantiles in a nonlinear ...
