An application of mixed-effect models to analyse contraceptive use in Malawian women

open access: yesContraception and Reproductive Medicine, 2019
In Malawi, the current approach to family planning using contraceptive methods is individualised, yet studies have shown that variability in contraceptive-use still remains after accounting for it at individual and household levels. Therefore, this study

Bench Plot and Mixed Effects Models: First steps toward a comprehensive benchmark analysis toolbox [PDF]

open access: yes, 2008
Benchmark experiments produce data in a very specific format. The observations are drawn from the performance distributions of the candidate algorithms on resampled data sets.

Derivative Computations and Robust Standard Errors for Linear Mixed Effects Models in lme4 [PDF]

open access: yes, 2017
While robust standard errors and related facilities are available in R for many types of statistical models, the facilities are notably lacking for models estimated via lme4.

Mixed Effects in Stochastic Differential Equation Models

open access: yesRevstat Statistical Journal, 2005
A class of statistical models is proposed where random effects are incorporated into a stochastic differential equations model, and an expression for the likelihood function is derived.

Linear Mixed Models with Marginally Symmetric Nonparametric Random Effects

open access: yes, 2016
Linear mixed models (LMMs) are used as an important tool in the data analysis of repeated measures and longitudinal studies. The most common form of LMMs utilize a normal distribution to model the random effects.

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).
