Linear Quantile Mixed Models: The lqmm Package for Laplace Quantile Regression [PDF]

open access: yesJournal of Statistical Software, 2014
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

Modelling subject-specific childhood growth using linear mixed-effect models with cubic regression splines [PDF]

open access: yesEmerging Themes in Epidemiology, 2016
Background Childhood growth is a cornerstone of pediatric research. Statistical models need to consider individual trajectories to adequately describe growth outcomes.

Study of Bayesian variable selection method on mixed linear regression models.

open access: yesPLoS ONE, 2023
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 ...

Quantile regression in linear mixed models: a stochastic approximation EM approach [PDF]

open access: yesStatistics and Its Interface, 2017
This paper develops a likelihood-based approach to analyze quantile regression (QR) models for continuous longitudinal data via the asymmetric Laplace distribution (ALD). Compared to the conventional mean regression approach, QR can characterize the entire conditional distribution of the outcome variable and is more robust to the presence of outliers ...

Model Selection in Linear Mixed Models [PDF]

open access: yes, 2013
Linear mixed effects models are highly flexible in handling a broad range of data types and are therefore widely used in applications. A key part in the analysis of data is model selection, which often aims to choose a parsimonious model with other ...

Polygenic modeling with bayesian sparse linear mixed models. [PDF]

open access: yesPLoS Genetics, 2013
Both linear mixed models (LMMs) and sparse regression models are widely used in genetics applications, including, recently, polygenic modeling in genome-wide association studies.

Estimating biomass of mixed and uneven-aged forests using spectral data and a hybrid model combining regression trees and linear models

open access: yesiForest - Biogeosciences and Forestry, 2016
The Sierra Madre Occidental mountain range (Durango, Mexico) is of great ecological interest because of the high degree of environmental heterogeneity in the area.

Non-linear and mixed regression models in predicting sustainable concrete strength

open access: yesConstruction and Building Materials, 2018
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 ...

Extension of the glmm.hp package to Zero-Inflated Generalized Linear Mixed Models and multiple regression

open access: yesJournal of Plant Ecology, 2023
glmm.hp is an R package designed to evaluate the relative importance of collinear predictors within generalized linear mixed models (GLMMs). Since its initial release in January 2022, it has rapidly gained recognition and popularity among ecologists ...
