st: Models ARIMA in STATA and Eviews

["Joao Ricardo F. Lima" <jricardo@cca.ufpb.br>]

Hi,

I have one doubt with models ARMA-ARIMA-SARIMA. When i'm using eviews, i
have one result. When i use Stata, the same model (ex arima y,
arima(2,1,2)), the results are different. Sometimes, very different!

Can help me and explais these differences, please?

Thanks,

Joao Lima
