This two day course with exercises will focus on fitting and interpreting mixed models in R, using the lme4 package.

  • Refresher: regression, (generalized) linear models, models for ordinal data
  • When to use mixed models: data structures, repeated measures
  • Why mixed models: regularization, plausibility, generalizability
  • Definition & theory of mixed models
  • Visualizing longitudinal & hierarchical data
  • Fitting models with lme4: syntax & helper functions
  • Inference with lme4: fixed effects, random effects, predictions
  • Model evaluation with lme4: model criticism, model selection
  • Troubleshooting: missingness patterns, non-convergence

Basic familiarity with R syntax and some experience with data analysis in R (loading data, fitting models, using the built-in graphics functions). Familiarity and some practical experience with regression modeling.

Participants should bring their own laptop with an up-to-date version of R with packages lme4, RLRsim, ordinal, ggplot2, and HSAUR installed. The RStudio IDE is recommended as well.
