Chapter 15 Hierarchical Models are Exciting

Welcome to Unit 4 - The final unit !

Hierarchical models expand our toolbox for hierarchical (grouped / pooled) data:

• a sampled group of schools and data \(y\) on multiple individual students within each school

• a sampled group of labs and data \(y\) from multiple individual experiments within each lab

• a sampled group of people on whom we make multiple individual observations of information \(y\) over time.

Unit four will explore these techniques in these final chapters:

• Chapter 15: Introduce the concepts

• Chapter 16: Hierarchical models without predictors

• Chapter 17: Normal Hierarchical Models with predictors

• Chapter 18: Non-Normal Hierarchical Regression

• Chapter 19: More Layers!
