I am working on a project in which i have to use BVAR to forecast tax revenue. I am using Eviews 7 with BVAR Add-ins but every time i do my analysis i get the following message "Near singular matrix. Precision of coefficients can not be estimated." Can you help me on how i can solve the problem and how to conduct the BVAR analysis.

Hi,

I am so greatful if anyone of you could help me with the maximum number of endogenous variables that the model can handle.
Is there a possibility to use 54 variables?
I think that the code allows only for 30 endogenous variables or this is a dialog box issue?
Could someone please guide me to find the BVAR code?

thanks

Try the lbvar add-in. it can handle 54 variables.
