Web完成后，用hausman检验，这个检验的原假说是iv回归与原回归（不用iv的回归）的变量的系数并没有显著的不同。 看一下P值，如果P小于比如说0.1，或者0.05，那么，说明IV回归与原来的回归显著不同，原来的方程的确有内生性问题导致的估计偏误。 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 …
