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 WebA seasonal ARIMA model is formed by including additional seasonal terms in the ARIMA models we have seen so far. 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.

The forecast for an MA (1) process is nonzero only for horizon h = 1. Thus you get a constant forecast (equal to the last observed value plus one value of MA (1) term) beyond h = 1.
