Generalized Methods of Moments

[slovakman]

HI all,

I am trying to do a Pooled OLS regression using the GMM method in EViews 7. When I run the regrsion it says Order condition violated - Insufficient instruments. It requires me to enter instruments under the Instruments tab in the Estimation Equation. Would like to ask you what are the Instruments?

Thanks!

Best
