WebFeb 11, 2016 · The command gmm is used to estimate the parameters of a model using the generalized method of moments (GMM). GMM can be used to estimate the parameters of models that have more identification conditions than parameters, overidentified models. The specification of these models can be evaluated using Hansen’s J statistic (Hansen, … WebThis test is the overidentifying restrictions test and the statistic is called the \(J\)-statistic with \[J \sim \chi^2_{m-k}\] in large samples under the null and the assumption of homoskedasticity. The degrees of freedom \(m-k\) state the degree of overidentification since this is the number of instruments \(m\) minus the number of endogenous …

WebThis is an example of an overidentified model, that is a model with positive degrees of freedom (as opposed to the previous models which can be described as saturated or just identified). Having positive degrees of freedom allows us to examine the fit of the model using the chi-squared test of model fit, along with fit indices, for example, CFI and RMSEA.
The Sargan–Hansen test or Sargan's $${\displaystyle J}$$ test is a statistical test used for testing over-identifying restrictions in a statistical model. It was proposed by John Denis Sargan in 1958, and several variants were derived by him in 1975.
