Re: Fitting an ARMA model
Thanks startz for your feedback. I was simply looking at the out-of-sample forecast to determine which model would fit the best. ARMA(1,(1,12)) has a very poor fit with correlated residuals and I was trying to come up with a better model. I was actually advised to use the Kalman filter to extract th...

I removed the posts from the Econometric Discussion section and now it only appear...
