[Gretl-users] ARMA with additional regressors - The symbol 'b0' is undefined
Dear forum,
when estimating an ARMA(x,y) model on my dataset, I receive a "The symbol
'b0' is undefined" error as soon as x > 0, regardless of y, and I have
nothing like b0 in my dataset. I tried googling, to no avail. What could be the problem?
Best regards,
Daniel
