Webmgreater than>k.It is not possible to statistically test the exogeneity of instruments when the coefficients are exactly identified; i.e., when mequals=k. In large samples, if the instruments are not weak and the errors are homoskedastic, then, under the null hypothesis that the instruments are exogenous, the J -statistic ... WebMay 19, 2024 · Identification is one of the essential and initial steps in estimating simultaneous equation models. If an equation or model is overidentified, tests of overidentifying restrictions must be applied to check the validity of instruments. When an equation or model is just or exactly-identified, such tests are not applicable. …
WebJun 17, 2015 · In the case of exactly identified models, he suggests setting the fnscale to a small number to force the optim minimizer to converge closer to 0. Also, he thinks the BFGS algorithm works better with GMM. summary (gmm (g, x, t0=rep (0,2), method = "BFGS", control=list (fnscale=1e-8))) Both solutions work for this example. Thanks Pierre! Share
