Variables limitation in VAR models

Postby Roman » Mon Apr 04, 2016 10:53 am

Hi Guys,

There is a limitation of 30 endogenous variables for VAR models (including BVAR). Is there a way to turn that off ?
If not, what do you recommend to overcome that ?

Thank you.

Regards,

Roman

It cannot currently be turned off. We will look into expanding it for future versions.

Hi Gareth,

Thanks for prompt reply. It is quite urgent for me to have that feature.
Do you think you could release this feature in a patch ?

No.

If you're just interested in simple VAR estimation, you could estimate in a system.

Unfortunately it is the BVAR I am interested in (need to shrink the system).
The only alternative that I see is calling R functions from the MSBVAR package...
