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

Extension of theglmm.hppackage 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 ...

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 ...

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

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.

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 ...

Insight into Genome-Wide Associations of Growth Trajectories Using a Hierarchical Non-Linear Mixed Model [PDF]

open access: yesBiology
In applying a hierarchical mixed model to genome-wide association analysis (GWAS) of longitudinal data, dimensionality reduction through modeling repeated measurements improves both computational efficiency and statistical power. Legendre polynomials can

Convergence of Parameter Estimates for Regularized Mixed Linear Regression Models [PDF]

open access: yes2019 IEEE 58th Conference on Decision and Control (CDC), 2019
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.

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.

Using Linear Mixed-Effects Models with Quantile Regression to Simulate the Crown Profile of Planted Pinus sylvestris var. Mongolica Trees

open access: yesForests, 2017
Crown profile is mostly related to the competition of individual trees in the stands, light interception, growth, and yield of trees. A total of 76 sample trees with a total number of 889 whorls and 3658 live branches were used to develop the outer crown
