Webb29 okt. 2024 · I will give a proof for a general GMM test statistic of overidentifying restrictions, which evaluates the GMM criterion function at the GMM estimate. The Sargan statistic is a special case of this statistic under conditional homoskedasticity. The notation and exposition follow Hayashi (2000) ... WebbThe results of the explicit $2SLS$ procedure are shown in Table 10.2; keep n mind, however, that the standard errors calculated in this way are incorrect; the correct method is to use a dedicated software function to solve an instrumental variable model.In $R$, such a function is ivreg(). fict/alt title/reg card/tag nc
