1: Introduction to Multilevel Models
The statistical analysis of clustered data. Random and fixed effects. Within-group and between-group variance. The intra-class correlation. Maximum likelihood and empirical Bayes estimates. A quick review of available software: MLwin, HLM, Stata and R. School effects in language scores.
2: Two-Level Models: Random Intercepts and Slopes
Random intercept models. Estimation using maximum likelihood (ML) and restricted maximum likelihood (REML). Likelihood ratio and Wald tests. Bayes estimates of group intercepts. Fixed and random-effect models revisited. Random slope models. Comparisons with group-specific regressions. Longitudinal and growth curve models.
