Hi there,

I've tried estimating a Structural VAR, only to get an error that the matrix I'm using is singular (hence it won't estimate). I'm assuming that it doesn't want to estimate because the matrix I'm trying to estimating can't invert? Is that correct?

Would a matrix be singular if my variables are too correlated? I have thought about using a VECM but not all of my variables are I(1).

If anyone has a potential solution, please let me know?

Thanks
