WebJan 18, 2024 · Since Stata automatically deletes the time-invariant regressors, they can't be estimated by ordinal methods like FE. In that case, we can use the Hausman-Taylor estimator, xthtaylor, a transformed Random Effect (RE) model with instrument variables (IV). This method should distinguish basically between time-varying and time-invariant …
