Hierarchical Models

When to Use

• Nested/grouped data (students in schools, patients in hospitals)
• Repeated measurements on subjects
• Meta-analysis with study-level variation
• Partial pooling between complete pooling and no pooling

Core Concept: Partial Pooling

Group means shrink toward overall mean based on:
- Within-group sample size
- Within-group variance
- Between-group variance
