How Do You Handle Missing Values in Panel Data Analysis? or What Are the Best Practices for Modeling

Panel data newbie here too! I struggled with this until my prof said: "If you care about within-group variation, use FE. If you care about between-group, use RE."

Hausman tests? R’s `plm` or Stata’s `xtreg`. Both have docs online.

P.S. Watch out for autocorrelation—it’s sneaky in panel data!
