@ShortAndLong with the NOESTIMATE option will code up a mapping from a set of underlying parameters to the "B" matrix that will give the required set of restrictions. The problem here is that there are other restrictions imposed on the "B" matrix that aren't just zero restrictio...

Thanks Tom for your reply. The exact reference is http://www.sciencedirect.com/science/ar ... 329090063A

I am trying a FIML on the lines of Keating (1990). I am not sure where Rats implements this with A restrictions.

Thanks Tom.

I am getting this error. Can't I do this.

Hi Tom,

One more thing, how can we get VAR coefficients after model. I am not talking about print. I mean how we can use them in writing constraints.

Hi Tom

What is the correct format of AFRML? As I am getting error "Identifier AFRML is Not Recognizable". Can I write one element as b(1)*-0.5 where b(1) is the element, I am going to estimate.

Thanks Tom. I got what are you saying. Please post if you remember any reference about how to check rank and order condition in this kind of setup.

Thanks Tom
I will put one more long run restrictions. That makes 15 variable to the right hand side, which can be identified using 15 free parameters in the left hand side Var-covar matrix of residual. Where am I wrong? I would be grateful if you can elaborate it a bit.

Tom Please have a look at this. Thanks for all your help.

Thanks Tom. If I am not wrong they are also saying that structural shock of demand and supply are correlated. They are using non-zero off diagonal element in "mu" matrix.

Thanks Tom.

Please find the attached file.

Thanks Tom.
In CVMODEL we can specify A and B. As far as I think there is no option of giving Var-Covar of Structural residual. In the Handbook it's written that it is assumed to be unit diagonal.

Thanks Tom.
I want to write Var-Covar(Reduced form Residual)=G* Var-covar(Structural Residual)*G'. From there I want to solve for G. My Var-covar(Structural Residual) is not unit diagonal? How can I do that? What about the Global Identification if I write and try to solve non-linear system?

Hi
Even I didn't get af matrix. Can you please write in terms of Var-Covar(Reduced form Residual)=G* Var-covar(Structural Residual)*G'. And then long run restrictions.
Many Thanks

Thanks Tom. How did we get this compute alpha=-.3,gamma=.3? Forgive my ignorance if any.
