Web30 ott 2014 · In our new jargon, we could call this model an ARIMA(0,0,0) model. Now, the ARIMA(1,1,1) model is merely obtained by adding bells and whistles to it. Instead of "Y t equals e t," the ARIMA(1,1,1) model asserts that "something times Y t" equals "something times e t." In particular: Including a first difference is equivalent to multiplying Y t Webalternative hypothesis model is the ARIMA (0,2,1) with θ close to –1. Under this situation, there are two available prediction equations for forecasting future values of the process; the first one is based on the true ARIMA (0,2,1) model, and the second one on the mathematical properties of the random walk model with drift.

It is written as follows: where m = m = number of observations per year. We use uppercase notation for the seasonal parts of the model, and lowercase notation for the non-seasonal parts of the model.
