Generalizing across stimuli as well as subjects: A non-mathematical tutorial on mixed-effects models [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2016
Although it has long been known that analyses that treat stimuli as a fixed effect do not permit generalization from the sample of stimuli to the population of stimuli, surprisingly little attention has been paid to this issue outside of the field of ...

Logistic mixed models to investigate implicit and explicit belief tracking [PDF]

open access: yes, 2016
We investigated the proposition of a two-systems Theory of Mind in adults’ belief tracking. A sample of N = 45 participants predicted the choice of one of two opponent players after observing several rounds in an animated card game. Three matches of this

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).

Investigations of a compartmental model for leucine kinetics using nonlinear mixed effects models with ordinary and stochastic differential equations

open access: yes, 2011
Nonlinear mixed effects models represent a powerful tool to simultaneously analyze data from several individuals. In this study a compartmental model of leucine kinetics is examined and extended with a stochastic differential equation to model non-steady

Best practice guidance for linear mixed-effects models in psychological science

open access: yesJournal of Memory and Language, 2019
The use of Linear Mixed Effects Models (LMMs) is set to dominate statistical analyses in psychological science and may become the default approach to analyzing quantitative data. The rapid growth in adoption of LMMs has been matched by a proliferation of

Novel Modelling Approaches to Characterize and Quantify Carryover Effects on Sensory Acceptability

open access: yesFoods, 2018
Sensory biases caused by the residual sensations of previously served samples are known as carryover effects (COE). Contrast and convergence effects are the two possible outcomes of carryover.

robustlmm : An R Package for Robust Estimation of Linear Mixed-Effects Models

open access: yes, 2016
As any real-life data, data modeled by linear mixed-effects models often contain outliers or other contamination. Even little contamination can drive the classic estimates far away from what they would be without the contamination.

D-optimal designs formulti-response linear mixed models [PDF]

open access: yes, 2018
Linear mixed models have become popular in many statistical applications duringrecent years. However design issues for multi-response linear mixed models are rarelydiscussed.

Generalized score test of homogeneity for mixed effects models

open access: yes, 2006
Many important problems in psychology and biomedical studies require testing for overdispersion, correlation and heterogeneity in mixed effects and latent variable models, and score tests are particularly useful for this purpose. But the existing testing
