### ARW add-in

This thread is about the ARW add-in that implements Arias, Rubio-Ramirez and Waggoner algorithm for sign and zero restricted VARs.

### Re: ARW add-in

Hi,

I just run the ARW add-in with the data provided in the add-in file. However, it shows the following warning:

Error 17 in encrypted program, and there is no any output about Figure 6: Importance Sampler Output.

May I know how can I fix this problem?

Thank you

Pascal

### Re: ARW add-in

What is the version of Eviews you use? It only works for the version 11.

### Re: ARW add-in

Dear dakila,

Thank you for your reply. I am using version 10.

Pascal

Thank you for your reply. I am using version 10.

Dear dakila,

May I know how can I obtain the forecast error of variance decomposition with its long horizon?

Thank you

Just try to estimate the FEVD with the different long horizon and check the convergence.

Dear Dakila,

When I try to estimate a zero and sign restricted VAR I always get error 15.

Do you know what might cause the problem?

I use these commands, I have 5 variables with monthly data.

matrix zeromatrix = @zeros(3,5)

zeromatrix(1,2)=1

zeromatrix(2,3)=1

zeromatrix(3,5)=1

matrix signmatrix =@zeros(2,5)

signmatrix(1,1)=1

signmatrix(2,4)=-1

arw(ndraws=1000, nsteps=24, horizons=2) 2 signmatrix zeromatrix @ lta lgdp lcp ciss lmro

### Re: ARW add-in

I have version 11, and the newest version of the Add-in

### Re: ARW add-in

If you don't know the restriction matrix syntax, you can use the dialogbox instead of command line

zero restriction matrix should be like this

matrix zeromatrix = @zeros(1,5)

zeromatrix(1,2)=1

zeromatrix(1,3)=1

zeromatrix(1,5)=1

zero restriction matrix should be like this

matrix zeromatrix = @zeros(1,5)

zeromatrix(1,2)=1

zeromatrix(1,3)=1

zeromatrix(1,5)=1
