2. Advanced Panel Data Methods 2 Panel Data Methods Last time: Panel data with more periods and fixed effects estimation. First-differencing with more than two periods (13.5) Within transformation (14.1) Dummy variable regression A simulated illustration Example: Job training grants. Today: Panel data with uncorrelated heterogeneity. Alternative data structures. Random effects (RE) model (14.2) Feasible Generalized least squares estimation: RE estimation Fixed or random effects? Alternative data structures (14.3): Matched pair samples, cluster samples.

14. Advanced Panel Data Methods 14 Next time Monday next week! Heino takes over the course and talks about Monte Carlo simulation and PcNaive. Next topics are:  A short introduction to time series  A block on more on general estimation methods (maximum likelihood and generalized methods of moments). Remember the exercises this week! Thanks for now! Use my contact information on the home page if you have questions about the panel data part.
