WebARIMA is a generalized model. Some of the models discussed in this chapter are special cases of an ARIMA model. For example, ARIMA (0,1,0) is expressed as yt=yt−1+ e. It is the naive model with error, which is called the Random walk model. ARIMA (0,1,0) is expressed as yt=yt−1+ e+ c. It is a random walk model with a constant trend.
