Course Objectives

A student completing this course should be able to: 1. Describe multilevel models as a generalization of linear regression models. 2. Describe multilevel models as a special case of a hierarchical Bayes model. 3. Build, fit, and evaluate multilevel and hierarchical models using classical and Bayesian methods. 4. Apply multilevel models to clustered sampling schemes, growth curves, random coefficient settings, and grouped experimental trials.
