  • Arima(p,d,q) forecasting equation: arima models are, in theory, the most general class of models for forecasting a time series which can be made to be “stationary” by differencing (if necessary), perhaps in conjunction with nonlinear transformations such as logging or deflating (if necessary) a random variable that is a time series is.
  • Arima has the limitations imposed by the model itself, ie the data must be generated from a linear combination of the previous values and the previous errors.
