Stata offers a wide range of commands for panel data analysis, including:

Note: The standard hausman command assumes homoskedasticity. If you are using robust or clustered standard errors, use the user-written xtoverid or vce(robust) combined with a Mundlak approach. 4. Diagnostic Testing for Panel Data : The pnardl module (available via SSC) extends

Stata allows for clustering at the panel level to adjust for within-group correlation.

If the test rejects the null hypothesis of homoskedasticity, you must adjust your standard errors. Autocorrelation (Serial Correlation) Stata offers a wide range of commands for

is purely random and uncorrelated with your regressors. It uses Generalized Least Squares (GLS) to weight the between and within variation.

To solve this endogeneity, you must use Difference GMM (Arellano-Bond) or System GMM (Blundell-Bond). These approaches use lags of the endogenous variables as instruments.

xtline is powerful for plotting trajectories for specific panels (e.g., specific firms over time).
