Fitting Linear Mixed-Effects Models Using lme4

open access: yesJournal of Statistical Software, 2015
Maximum likelihood or restricted maximum likelihood (REML) estimates of the parameters in linear mixed-effects models can be determined using the lmer function in the lme4 package for R. As for most model-fitting functions in R, the model is described in

Generalized linear mixed models can detect unimodal species-environment relationships [PDF]

open access: yesPeerJ, 2013
Niche theory predicts that species occurrence and abundance show non-linear, unimodal relationships with respect to environmental gradients. Unimodal models, such as the Gaussian (logistic) model, are however more difficult to fit to data than linear ...

Modified BIC Criterion for Model Selection in Linear Mixed Models

open access: yesMathematics, 2023
Linear mixed-effects models are widely used in applications to analyze clustered, hierarchical, and longitudinal data. Model selection in linear mixed models is more challenging than that of linear models as the parameter vector in a linear mixed model ...

lmerTest Package: Tests in Linear Mixed Effects Models

open access: yesJournal of Statistical Software, 2017
One of the frequent questions by users of the mixed model function lmer of the lme4 package has been: How can I get p values for the F and t tests for objects returned by lmer?

Accessible analysis of longitudinal data with linear mixed effects models

open access: yesDisease Models & Mechanisms, 2022
Longitudinal studies are commonly used to examine possible causal factors associated with human health and disease. However, the statistical models, such as two-way ANOVA, often applied in these studies do not appropriately model the experimental design,

Clustering in linear mixed models with a group fused lasso penalty [PDF]

open access: yes, 2012
A method is proposed that aims at identifying clusters of individuals that show similar patterns when observed repeatedly. We consider linear mixed models which are widely used for the modeling of longitudinal data.
