Re: Interpreting results after taking first differences

The important thing is to remain as consistent as possible, if one of your variables is in percentage then all others should also be percentage. Second, why are you taking first differences? usually the reason is that you have non-stationary variables. For interpretation on the other hand, you shoul...

Hello there, I am trying to restricted to allow restrictions on the constant term in a VEC estimation. I am not familiar with coding and EVIEWS does not allow restrictions on the constant term to be placed from the dialog. I have 6 endogenous variables, and 9 time-dummies. Any Help is greatly apprec...

In order to do so, I set up a VAR which I estimated, and went to VAR Granger Causality/Block Exogeneity Wald Tests.

VAR lags

Hello,

I am trying to estimate a VAR in first differences. I only need one endogenous variable for my model, and I am trying to input D(X(0 to -7)) in exogenous but eviews returns "0TO-7 is not a valid index for DX". What could be wrong here? I can't seem to find the problem.
