Re: Threshold Structural VAR
Hi,
I am using eviews 10 demo license and I have installed thsvar add in but once I specify the thsvar model using the box options and press ok using the box options it is telling me that Eviews 10 has stopped working.
What is the problem,please?

Re: Threshold Structural VAR
I think problem is that you are using the demo version.
Re: Threshold Structural VAR
Ok, but there was a time using the demo version of Eviews 9,I was using threshold svar add in without any problem.
Thanks.

Thanks.

Re: Threshold Structural VAR
Hello, i want to know the code of THSVAR,when i select File/open/Programs in addin folder... and open the THSVAR folder and click thsvar.prg,why the dialog display "Encrypted program". How should i do if i want to understand the thsvar.prg(in order to modify THSVAR code to adapt my model )? Thanks.

Hello,
Addin authors have the option to encrypt and conceal their programs if they wish. This ability isn't unique to addins, any EViews program can be encrypted. If you're interested in how a program works and/or obtaining the unencrypting source for the program, you can contact the addin author through the appropriate forum or via any contact information provided with the addin's documentation. Just keep in mind that the author chose to encrypt the program for a reason, so there's no guarantee he or she will share the source with you.

Hi,
In the balke paper,it says the threshold value is the one that maximizes the log determinant of the structural residuals.But here ,in the add in ,I read the result as specification that minimizes the log determinant.So,is there any difference between this two points? could you give me a general intuition about this,please?
And the second I think we are also using the Tsay test that is avg wald and expwald besides to the hansen test that is supwald or LRsup.Hence,can you give me also some ideas about the Hansen and Tsay tests,please? What exactly are we doing with regard to these two tests?

Re: Threshold Structural VAR
Hello, thanks for the useful addin.
Is there a way to calculate a 1 percent shock instead of a 1 standard deviation shock?
The problem is that my threshold variable is inflation growth rate, and it's standard deviation is 0.59, so doing a 59% shock is not an useful exercise
Is the response measured in standard deviations too?
Thanks in advance,
Best regards

No. there is no difference between these two points.

I don't know Tsay test.
Re: Threshold Structural VAR

I think there is no way to do so. Because Balke's Threshold VAR model is nonlinear. So it is not scalable.

If your variable is in log then response is in percentage change. I think 0.59 is 0.59 % shock.

Hi,
when i want to run the Add in in eviews 10 demo, it tells me that syntax error.What is that,please?

Re: Threshold Structural VAR
Thank you Dakila for your answer.
Is there a way to obtain the VAR estimation for each regime instead of different outputs for each dependent variable?
It will be useful to get the variance/covariance matrix for each regime, also the Rsquared of the VAR estimation.
Best regards,
Edgar

It is a bug for Eviews 10. It is fixed. Just update the thsvar addin.
Re: Threshold Structural VAR

It is indeed the VAR estimation. If read any textbook on VAR, it will tell that VAR estimation equal to OLS estimation of each dependent variable equation.

Hi,
What is the degree of freedom adjustment? The default value in the dialog box is 0.Can I simply estimate my threshold SVAR model as in the default value with out modification to the degree of freedom,please? What would be the implication of this for my thsvar model?

Re: Threshold Structural VAR
The degrees of freedom adjustment is used to compute the threshold value which is excluded at the beginning and the end of sample.
The formulae: b = ob*(endstart+1)+nvardfa
 ob = fraction of buffer period
 start = start of sample
 end = end of sample
 nvar = number of variable
 dfa = degrees of freedom
