Forecasting Process Details
Parameter Estimation
The parameter estimation process for ARIMA and smoothing models is described graphically in Figure 61.1.

The specification of smoothing and ARIMA models is described in Chapter 56: Specifying Forecasting Models. Computational details for these kinds of models are provided in the following sections Smoothing Models and ARIMA Models. The results of the parameter estimation process are displayed in the Parameter Estimates table of the Model Viewer windows along with the estimate of the model variance and the final smoothing state.
