Meta-analysis in psychological research.

open access: yesInternational Journal of Psychological Research, 2010
Meta-analysis is a research methodology that aims to quantitatively integrate the results of a set of empirical studies about a given topic. With this purpose, effect-size indices are obtained from the individual studies and the characteristics of the ...

Comparison of Three Mixed-Effects Models for Mass Movement Susceptibility Mapping Based on Incomplete Inventory in China

open access: yesRemote Sensing, 2022
Generating an unbiased inventory of mass movements is challenging, particularly in a large region such as China. However, due to the enormous threat to human life and property caused by the increasing number of mass movements, it is imperative to develop

Kriging with mixed effects models

open access: yesStatistica, 2007
In this paper the effectiveness of the use of mixed effects models for estimation and prediction purposes in spatial statistics for continuous data is reviewed in the classical and Bayesian frameworks. A case study on agricultural data is also provided.

Parameter identifiability of fundamental pharmacodynamic models

open access: yesFrontiers in Physiology, 2016
Issues of parameter identifiability of routinely used pharmacodynamics models are considered in this paper. The structural identifiability of 16 commonly applied pharmacodynamic model structures was analysed analytically, using the input-output approach.

Peer Effects on Vocabulary Knowledge: A Linear Quantile Mixed-Modeling Approach

open access: yesEducation Sciences, 2018
Do your peers in the classroom have an effect on your vocabulary learning? The purpose of this study was to determine if group-level peer characteristics and group-level peer achievement account for individual-level differences in vocabulary achievement ...

Species Distribution Modeling: Comparison of Fixed and Mixed Effects Models Using INLA

open access: yesISPRS International Journal of Geo-Information, 2017
Invasive alien species are among the most important, least controlled, and least reversible of human impacts on the world’s ecosystems, with negative consequences affecting biodiversity and socioeconomic systems. Species distribution models have become a

Filling the Gap Between Implicit Associations and Behavior: A Linear Mixed-Effects Rasch Analysis of the Implicit Association Test

open access: yesMethodology, 2022
The measure obtained from the Implicit Association Test (IAT; Greenwald et al., 1998. DOI: 10.1037/0022-3514.74.6.1464) is often used to predict people’s behaviors.

Cross-Validation for Nonlinear Mixed Effects Models [PDF]

open access: yes, 2013
Cross-validation is frequently used for model selection in a variety of applications. However, it is difficult to apply cross-validation to mixed effects models (including nonlinear mixed effects models or NLME models) due to the fact that cross ...

Extension of Nakagawa & Schielzeth's R2GLMM to random slopes models [PDF]

open access: yes, 2014
1.Nakagawa & Schielzeth extended the widely used goodness-of-fit statistic R2 to apply to generalized linear mixed models (GLMMs). However, their R2GLMM method is restricted to models with the simplest random effects structure, known as random ...
