Hi again With arima0 the problem was solved but what are the diferences between arima and arima0?
I have another question. I fit the model to the data and I make some predictions. But I also want to calculate MAPE based in the last 3 observations available. Is it possible? Can I obtain the fitted values from the model? thanks~ luis -- SAPO ADSL.PT, apanhe j� o comboio da Banda Larga.
