Stata Panel Data Jun 2026

To work with panel data in Stata, follow these steps:

Result: F(1,29) = 14.72, Prob > F = 0.001 → Serial correlation present.

To analyze panel data in Stata, you need to set up your data in a specific format. Each observation should represent a single unit (e.g., individual) at a particular point in time. The data should have the following structure: To work with panel data in Stata, follow

The Random Effects model assumes that the variation across entities is random and uncorrelated with the independent variables included in the model. Unlike FE, RE allows you to include time-invariant variables (like gender) as explanatory variables. xtreg y x1 x2, re Choosing Between FE and RE: The Hausman Test

: Clean and import your dataset, then explicitly declare the panel structure using xtset . 2. Explore & Balance : Use xtdescribe and xtsum to understand gaps and variation, addressing issues like duplicates or missing time points. 3. Estimate Model : Start with benchmark xtreg, fe and xtreg, re models, performing the Hausman test to guide your initial choice. 4. Address Endogeneity : If concerns exist (e.g., reverse causality), advance to xtivreg or dynamic GMM estimators, carefully evaluating instrument validity. 5. Validate & Robustness : Perform diagnostic tests for serial correlation, use robust standard errors, and test the sensitivity of your results to model specification.

If your data is in a wide format, you can convert it to a long format using the reshape command: reshape long income, i(id) j(year) Use code with caution.
