constructing impulse matrixes

[Financer]

Hello,

When I construct IRF after estimating VAR, it shows response of variables to cholesky 1 S. D.

I need to compare certain impulses to each other and for this I need either to divide response (change in variable) by (size) of initial shock or find responses to 1% shock.

My problem is that I don't know how to find this initial shock in variable in eviews, and I don't know how to construct impulse matrix that would be 1% shock.

I hope you will be able to understand :D and help me.

Thanks.

Assuming that you have 3 endogenous variables, you should first create a matrix (or vector if you like):

Code: Select all

matrix(3,3) impulse

You can then edit the matrix and enter your own impulses columnwise. Leave the remaining columns as NA. Select "Impulse/Impulse Definition" in the VAR object toolbar and enter the name of your matrix (or vector) into the "User Specified" edit box. You can obtain the values by selecting "Table" in the "Display/Display Format" tab.

Yes I made that matrix. And I got response of variables to this shock. But I didn't get this: how to control to which variable belongs this shock?

SO I could get IRF to shocks in all variables.

Thanks.
