Problem with estimation
Posted: Tue Apr 05, 2011 7:34 am
There might be a very simple explanation for the problem we are having but we can't find the answer.
We are trying to estimate (by OLS) the following model:
Mt = K(y) Yt + K(Tau) T - K(i) It + Sommation from s=-3 to 3 ( (K(y)^s)*d(y(t+s)) + (K(i)^s)*d(i(t+s)) ) + Et
where Et=residuals, K(y), K(Tau) and K(i) are the parameters to be estimated.
The problem is getting this formula into Eviews (Version 7). So far we have:
M = C(1)*Yt - C(2)*It + C(3)*T + C(1)^(-3)*d(Yt(-3)) + C(1)^(-2)*d(Yt(-2)) + C(1)^(-1)*d(Yt(-1)) + d(Yt) + C(1)*d(Yt(1)) + C(1)^(2)*d(Yt(2)) + C(1)^(3)*d(Yt(3)) + C(2)^(-3)*d(It(-3)) + C(2)^(-2)*d(It(-2)) + C(2)^(-1)*d(It(-1)) + d(It) + C(2)*d(It(1)) + C(2)^(2)*d(It(2)) + C(2)^(3)*d(It(3))
where C(1) = K(y), C(2) = K(i) and C(3)=K(Tau).
The results are clearly wrong and we were wondering whether or not this is because of our 'translation' into eviews is wrong....
We don't know how else to make the coefficients Ky and Ki reappear in the sommation. Suggestions?
Any help would be more than welcome since we have a deadline!
Thank you!
