Hi there,
I'd like to resort generalized methods of moment to estimate a regression model but I can't understand the help file of gmm package. If the regression model is y, the instrumental variable is x, how can I write the code? By the way, I use systemfit's 3sls with method3sls='GMM', but I can't get the suitable results. Many thanks.
