ivgmm0 estimates a linear regression model containing endogenous regressors via a generalized method of moments instrumental variables estimator (GMM-IV) that allows for heteroskedasticity of unknown form, with a command syntax matching that of ivreg. If the equation is overidentified by an abundance of instruments, a test of overidentifying restrictions--Hansen's "J" statistic--is provided to evaluate the validity of the model. The specification of this routine as ivgmm0 is meant to highlight its ability to deal with a heteroskedastic error process (at lag 0), but not with autocorrelation of unknown form (for which see ivreg2). This is version 1.1.12 of the software.
