Fixed or random? On the reliability of mixed‐effects models for a small number of levels in grouping variables [PDF]

open access: yesEcology and Evolution, 2022
Biological data are often intrinsically hierarchical (e.g., species from different genera, plants within different mountain regions), which made mixed‐effects models a common analysis tool in ecology and evolution because they can account for the non ...

Fiducial Inference in Linear Mixed-Effects Models [PDF]

open access: yesEntropy
We develop a novel framework for fiducial inference in linear mixed-effects (LME) models, with the standard deviation of random effects reformulated as coefficients.

Practical identifiability in the frame of nonlinear mixed effects models: the example of the in vitro erythropoiesis [PDF]

open access: yesBMC Bioinformatics, 2021
Background Nonlinear mixed effects models provide a way to mathematically describe experimental data involving a lot of inter-individual heterogeneity.

Mixed effects regression models in forestry research [PDF]

open access: yesСибирский лесной журнал, 2021
A promising method for finding patterns in experimental data is regression models of mixed effects, which have not found wide application in forest science in Russia to date.

Invited review: Recursive models in animal breeding: Interpretation, limitations, and extensions

open access: yesJournal of Dairy Science, 2023
: Structural equation models allow causal effects between 2 or more variables to be considered and can postulate unidirectional (recursive models; RM) or bidirectional (simultaneous models) causality between variables.

Biological and statistical interpretation of size-at-age, mixed-effects models of growth [PDF]

open access: yesRoyal Society Open Science, 2020
The differences in life-history traits and processes between organisms living in the same or different populations contribute to their ecological and evolutionary dynamics.

Using linear mixed models to analyze learning processes within sessions improves detection of treatment effects: An exemplary study of chronometric mental rotation

open access: yesMethods in Psychology, 2022
Practice effects occur for many cognitive tasks. They are observed not only between repeated tests, but also within sessions. They can confound the detection of treatment effects, even when compared with control groups.

Mixed effects envelope models

open access: yesStat, 2020
When multiple measures are collected repeatedly over time, redundancy typically exists among responses. The envelope method was recently proposed to reduce the dimension of responses without loss of information in regression with multivariate responses. It can gain substantial efficiency over the standard least squares estimator.
