Chapter 2: Planning a multilevel model Luke, D. (2020). Chapter 2. Planning a multilevel model. Multilevel modeling: Second Edition (pp. 9-15). SAGE Publications, Inc.
This chapter discusses the basics of a two-level multilevel model and the importance of random effects. The goal of a multilevel model is to predict values of some dependent variable based on a function of predictor variables at more than one level. For example, we might want to examine how a child’s score on a standardized reading exam is influenced both by characteristics of the child (e.g., amount of study time) as well as characteristics of the child’s classroom (e.g., size of class). In this example, we consider the child to be measured and modeled at Level 1, and the classroom at Level 2.
