CytoGLMM: conditional differential analysis for flow and mass cytometry experiments

open access: yesBMC Bioinformatics, 2021
Background Flow and mass cytometry are important modern immunology tools for measuring expression levels of multiple proteins on single cells. The goal is to better understand the mechanisms of responses on a single cell basis by studying differential ...

Multiple testing correction in linear mixed models. [PDF]

open access: yes, 2016
BackgroundMultiple hypothesis testing is a major issue in genome-wide association studies (GWAS), which often analyze millions of markers. The permutation test is considered to be the gold standard in multiple testing correction as it accurately takes ...

Generalized fiducial inference for normal linear mixed models [PDF]

open access: yes, 2012
While linear mixed modeling methods are foundational concepts introduced in any statistical education, adequate general methods for interval estimation involving models with more than a few variance components are lacking, especially in the unbalanced ...

Bayesian Linear Mixed Models with Polygenic Effects

open access: yesJournal of Statistical Software, 2018
We considered Bayesian estimation of polygenic effects, in particular heritability in relation to a class of linear mixed models implemented in R (R Core Team 2018).

Bayesian Inference for Spatial Beta Generalized Linear Mixed Models [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2018
In some applications, the response variable assumes values in the unit interval. The standard linear regression model is not appropriate for modelling this type of data because the normality assumption is not met. Alternatively, the beta regression model

Fast and flexible linear mixed models for genome-wide genetics. [PDF]

open access: yesPLoS Genetics, 2019
Linear mixed effect models are powerful tools used to account for population structure in genome-wide association studies (GWASs) and estimate the genetic architecture of complex traits.

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 ...

Linear Mixed Models: Gum and Beyond

open access: yesMeasurement Science Review, 2014
In Annex H.5, the Guide to the Evaluation of Uncertainty in Measurement (GUM) [1] recognizes the necessity to analyze certain types of experiments by applying random effects ANOVA models.

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 ...
