Structural Equation Models
Widely used in social and behavioral sciences, structural equation models (SEM) provide a highly valuable framework for integrating measurement and mediation analysis into statistical modeling. An SEM allows linking latent (or unobserved) variables to observed ones in order to address measurement error. It also permits the specification of multiple dependent variables simultaneously and an assessment of mediation based on the decomposition of total effects into direct and indirect effects. This course emphasizes the intuition behind SEMs and their applications. Examples, exercises, and code (R or Stata) will be provided. Knowledge of R (or Stata) and linear regression is required.
Day 1: Introduction, Effect Decomposition, and Mediation Analysis
Day 2: Latent Variables and Measurement Models
Day 3: General SEMs and Extensions
