Stata Panel Data [best]

Example:

xtreg wage hours tenure, fe vce(bootstrap, reps(200)) stata panel data

If the assumption of zero correlation between the unobserved entity traits and your predictors is violated, the estimates become biased and inconsistent. 4. Model Selection: Choosing the Right Estimator Example: xtreg wage hours tenure

Panel data estimation typically revolves around three core frameworks: Pooled OLS, Fixed Effects, and Random Effects. Pooled OLS Regression u // Individual effects predict fe_resid

predict fe_u, u // Individual effects predict fe_resid, e // Residuals predict fe_xb, xb // Linear prediction

For cross-sectional dependence (e.g., spatial or macroeconomic shocks):

For long panels (large T):
