Model Estimation SARAR(1, 1): Generalized Method of Moments l Moment Functions (Kelejian and Prucha, 1998, 2009)
Model Estimation SARAR(1, 1): Generalized Method of Moments l l Sample moment functions are the same two equations of one parameter r as in the spatial error AR(1) model. The efficient GMM estimator follows exactly the same as the spatial error AR(1) model with the IV estimator of the spatial lag model.
Model Estimation SARAR(1, 1) l l l The Model Estimate l, b and r simultaneously: QML Estimate l, b and r iteratively: IV/GMM/GLS l l l IV or 2 SLS GMM GLS
