Choosing the right model depends on your assumptions about "unobserved heterogeneity"—factors unique to individuals that don't change over time (like innate ability or geography).
For complex data issues, Stata provides specialized estimators.

Stata handles both gracefully, but you need to be aware of the distinction because estimation methods treat missing data differently.

Proper data management is crucial for panel data analysis. You will often need to reshape datasets, create lags, and generate new variables.
Stata makes it easy to mathematically determine which of the three models is most appropriate for your data.
