Boosting Ridge Regression [PDF]

open access: yes, 2005
Ridge regression is a well established method to shrink regression parameters towards zero, thereby securing existence of estimates. The present paper investigates several approaches to combining ridge regression with boosting techniques.

Multicollinearity and Linear Predictor Link Function Problems in Regression Modelling of Longitudinal Data

open access: yesMathematics, 2023
In the longitudinal data analysis we integrate flexible linear predictor link function and high-correlated predictor variables. Our approach uses B-splines for non-parametric part in the linear predictor component.

Bayesian Tobit quantile regression using-prior distribution with ridge parameter [PDF]

open access: yes, 2014
A Bayesian approach is proposed for coefficient estimation in the Tobit quantile regression model. The proposed approach is based on placing a g-prior distribution depends on the quantile level on the regression coefficients.

Nonlinear Generalized Ridge Regression

open access: yes, 2023
A Two-Stage approach is described that literally "straighten outs" any potentially nonlinear relationship between a y-outcome variable and each of p = 2 or more potential x-predictor variables. The y-outcome is then predicted from all p of these "linearized" spline-predictors using the form of Generalized Ridge Regression that is most likely to yield ...

Application of an Intensive Longitudinal Functional Model with Multiple Time Scales in Objectively Measured Children’s Physical Activity

open access: yesMathematics, 2023
This study proposes an intensive longitudinal functional model with multiple time-varying scales and subject-specific random intercepts through mixed model equivalence that includes multiple functional predictors, one or more scalar covariates, and one ...

Nonparametric Generalized Ridge Regression

open access: yes, 2023
The title of this paper is potentially misleading, its methods are neither innovative nor easy to apply, and its numerical example is nearly ...

The Efficiency of the K-L Estimator for the Seemingly Unrelated Regression Model: Simulation and Application

open access: yesJournal of Nigerian Society of Physical Sciences, 2023
This paper considers the Ridge Feasible Generalized Least Squares Estimator (RFGLSE), Ridge Seemingly Unrelated Regression RSUR and proposes the Kibria-Lukman KLSUR estimator for the parameters of the Seemingly Unrelated Regression (SUR) model when the ...

Penalized Regression with Ordinal Predictors [PDF]

open access: yes, 2008
Ordered categorial predictors are a common case in regression modeling. In contrast to the case of ordinal response variables, ordinal predictors have been largely neglected in the literature. In this article penalized regression techniques are proposed.

Comparison of Some Suggested Estimators Based on Differencing Technique in the Partial Linear Model Using Simulation

open access: yesمجلة بغداد للعلوم, 2019
In this paper new methods were presented based on technique of differences which is the difference- based modified jackknifed generalized ridge regression estimator(DMJGR) and difference-based generalized  jackknifed ridge regression estimator(DGJR), in ...

LASSO type penalized spline regression for binary data

open access: yesBMC Medical Research Methodology, 2021
Background Generalized linear mixed models (GLMMs), typically used for analyzing correlated data, can also be used for smoothing by considering the knot coefficients from a regression spline as random effects.
