Dear all,
I read a lecture notes on Time Series Analysis. This document gives me loads of examples, however, I don't understand why they choose the Arima (0,1,1)x(0,1,1)12 for the case.
I attached the following .doc file, which a print-screened one from the original file. Please help me know why they choose the model based on reading ACF and PACF graphs.
Thank you all in advance!
