no valid observations in equation

Postby cherish » Tue Dec 17, 2013 3:06 am

I did GMM estimation successfully with the following specifications. However when I tried to run it again, EViews responded with an error message: "no valid observations in equation "lcb=c(1)+c(2)*lcb(-1)+c(3)*cap+c(4)*cr+c(5)*lsize". I don't understand as the data is fine (I verified this by viewing "spreadsheet"). I've been using EViews for a while but am new to GMM. Could you help me please please.

lcb=c(1)+c(2)*lcb(-1)+c(3)*cap+c(4)*cr+c(5)*lsize
cap=c(6)+c(7)*lcb+c(8)*cap(-1)+c(9)*cr+c(10)*lsize
INST lcb(-1 to -2) cap(-1 to -2)

Bad starting values. Try setting c=1 before hand.
