WebJan 1, 2012 · This paper suggests a robust Hausman and Taylor (1981) estimator, here-after HT, that deals with the possible presence of outliers. This entails two modi cations of the classical HT estimator. WebJun 1, 2003 · A pretest estimator for the Hausman–Taylor model. Consider the Hausman and Taylor (1981) model which can be written as follows: y it =X it β+Z i η+α i +u it where i=1, 2,…,N and t=1, 2,…,T. The Z i are individual time-invariant variables. α i is IID(0, σ α 2) whereas u it is IID(0, σ u 2) both independent of each other and among ...
