Linear mixed-effects models workshop

This is an introductory 2 hours course on linear multilevel models using R and the lme4 library.

See the slides online here mlisi.xyz/RHUL-stats/workshops.html.

Outline

• Part 1: introduction to LMM and lme4 package
• Part 2:
  1. Estimation methods, ML and REML
  2. Parametric bootstrapping
  3. Power analyses via fake-data simulation
  4. Convergence warnings

The folder exercises contains some worked examples and exercises.

The slides are compiled using the xaringan library. If you want to compile them locally, you may have first to run some code bits (in particular code_bits_part2.R) for the second part of the course, as these generate comutationally demanding outpurs such as bootstrap distributions of simulations. (you may have to change the path to that of your machine)
