Study of Bayesian variable selection method on mixed linear regression models.
Variable selection has always been an important issue in statistics. When a linear regression model is used to fit data, selecting appropriate explanatory variables that strongly impact the response variables has a significant effect on the model ...

Linear Quantile Mixed Models: The lqmm Package for Laplace Quantile Regression [PDF]
Inference in quantile analysis has received considerable attention in the recent years. Linear quantile mixed models (Geraci and Bottai 2014) represent a ?exible statistical tool to analyze data from sampling designs such as multilevel, spatial, panel or

Convergence of Parameter Estimates for Regularized Mixed Linear Regression Models [PDF]
We consider {\em Mixed Linear Regression (MLR)}, where training data have been generated from a mixture of distinct linear models (or clusters) and we seek to identify the corresponding coefficient vectors. We introduce a {\em Mixed Integer Programming (MIP)} formulation for MLR subject to regularization constraints on the coefficient vectors.

Body temperature correlates with depressive symptom severity: analysis and extension of prior findings in observational cohorts with more than 19,000 participants [PDF]
ObjectivePrior studies have reported that higher body temperature correlates with greater depressive symptoms, but did not adjust for potential confounders.MethodsWe used linear regression models and linear mixed models to assess associations between ...

Non-linear and mixed regression models in predicting sustainable concrete strength
Abstract Most previous research adopting the regression analysis to capture the relationship between concrete properties and mixture-design-related variables was based on the linear approach with limited accuracy. This study applies non-linear and mixed regression analyses to model properties of environmentally friendly concrete based on a ...

On the mixed Kibria–Lukman estimator for the linear regression model
AbstractThis paper considers a linear regression model with stochastic restrictions,we propose a new mixed Kibria–Lukman estimator by combining the mixed estimator and the Kibria–Lukman estimator.This new estimator is a general estimation, including OLS estimator, mixed estimator and Kibria–Lukman estimator as special cases. In addition, we discuss the
