Dear all,

I have a question about ARIMA models. Let us consider, for example, an ARIMA(3,1,3) for the time series y(t). The parameters are estimated using the Conditional Maximum Likelihood, so I use

arima 3 1 3 ; y --conditional

In this case the convergence criterion was not met. I'd like change the convergence tolerance, is it possible?

Thanks.

Best regards

Alessandro
