Dear support team,

I have recently done GMM estimation for 1954q1-2010q4 using the same eq01 and eq02 and two systems in attached file. But when I tried to estimate GMM using updated data up to 2012 I get the following error: division by zero. I have tried different options but none of them works. I need to estimate the GMM for 9 different sub-samples but the same error comes up when I try to estimate.

I appreciate your help.

Regards,
Somayeh
