Cointegration

Hi everybody, Since we don't understand that much of Eviews, we need your help. We're trying to estimate the income elasticity by modelling the money demand. I have the following equation: RMBt = 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 w...

Re: Problem with estimation

That's the problem, I'm not sure we need starting values. We need estimates for the parameters that stay the same no matter how many times we press specify equation.
Should I try to do it in some other way or is the equation above correct?
Thx

Re: Output on Eviews changes

Maybe it's best if I elaborate.The equation we are using is this: RMB = C(1)*GDP - C(2)*SPREAD + C(3)*TIME + C(1)^(-3)*d(GDP(-3)) + C(1)^(-2)*d(GDP(-2)) + C(1)^(-1)*d(GDP(-1)) + d(GDP) + C(1)*d(GDP(1)) + C(1)^(2)*d(GDP(2)) + C(1)^(3)*d(GDP(3)) + C(2)^(-3)*d(SPREAD(-3)) + C(2)^(-2)*d(SPREAD(-2)) + C(...

Output on Eviews changes

Hello, when we put our data into eviews, one day we get a totally different result than another day. Also, given a time series of +- 50 observations, a result appears. If we add the next observation (which does not deviate that much from the previous ones), again our results change drastically. How ...

Problem with estimation

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) ...
