WebVideo for Econometrics II course at the University of Copenhagen (Department of Economics). WebSep 13, 2015 · GMM (Generalized Method of Moments) is one such method and it is more robust (statistically and literally [for non-statistics audience]) than several others. It should be intuitive that the process of estimation involves how good your model fits the data. The GMM uses more conditions than the ordinary models while doing this.
