Mixed Effects Modeling Lab (McNeish)

McNeish Lab

Lab Research Area:

The Mixed Effects Modeling Lab focuses on development, evaluation, and application of statistical methods to appropriately model data that come from a correlated data structure. Examples of such structures include students nested within schools, patients nested within hospitals, and repeated measures nested within people. In particular, the lab’s research focuses on modeling small sample data, missing data, Bayesian estimation, and extending mixed effects models to novel situations where they may possess untapped advantages.

Frequent Collaborators

Denis Dumas, Denis Dumas is an Assistant Professor in the Department of Research Methods and Information Science at the University of Denver. Denis’s research focuses on learning trajectories and non-linear models. Denis and Dan together created a non-linear mixed effect model for educational assessment scores and have published multiple papers on its formulation and application.

Rens van de Schoot, Rens is an Associate Professor in the Department of Methodology & Statistics at Utrecht University in the Netherlands and extra-ordinary professor at North-West University in South Africa. Rens’s research focuses on small sample inference and Bayesian statistics. Rens and Dan regularly give workshops and short courses on statistical topics including small sample analysis, Bayesian statistics, and structural equation modeling. They have also co-organized two statistical conferences together.

This list is limited to papers in Multivariate Behavioral Research, Psychological Methods, or Structural Equation Modeling since 2016. A complete list may be found in Dan’s CV [link to CV].
