I am just beginning working on ARIMA and SARIMA, and I have quite a number of questions:
1. I have to analyse the same set of data with both ARIMA and SARIMA, will the "p,q,d" parameters the same for both methods? 2. I have a set of data which shows seasonality, but I HAVE TO analyse it with ARIMA rather than SARIMA, so what could I do to fit the ARIMA model when the ACF and PACF show high positive valus in lag 12? Thanks so much for your kindly advice. . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
