Local Dimensionality Reduction for Non-Parametric Regression [PDF]

open access: yesNeural Processing Letters, 2009
Locally-weighted regression is a computationally-efficient technique for non-linear regression. However, for high-dimensional data, this technique becomes numerically brittle and computationally too expensive if many local models need to be maintained simultaneously.

Testing the Equality of Two Parametric Quantile Regression Curves : The Application for Comparing Two Data Sets [PDF]

open access: yes, 2016
This study aims to  compare the different between two data sets that having the relationship between the dependent and independent variables at each quantile using  testing the equality of  two parametric quantile regression functions, the conditional ...

On the pitfalls of Gaussian likelihood scoring for causal discovery

open access: yesJournal of Causal Inference, 2023
We consider likelihood score-based methods for causal discovery in structural causal models. In particular, we focus on Gaussian scoring and analyze the effect of model misspecification in terms of non-Gaussian error distribution. We present a surprising

Integration of association statistics over genomic regions using Bayesian adaptive regression splines

open access: yesHuman Genomics, 2003
In the search for genetic determinants of complex disease, two approaches to association analysis are most often employed, testing single loci or testing a small group of loci jointly via haplotypes for their relationship to disease status.

A better alternative to non-parametric approaches for adjusting for covariate measurement errors in logistic regression.

open access: yes, 2016
In this article, we propose a flexible parametric (FP) approach for adjusting for covariate measurement errors in regression that can accommodate replicated measurements on the surrogate (mismeasured) version of the unobserved true covariate on all the ...

Beta-Stacy survival regression models [PDF]

open access: yes, 2007
This paper introduces a class of survival models for discrete time-to-event data with random right censoring. Flexible distributions for the survival times are constructed by modelling the random survival functions as discrete-time beta-Stacy processes (
