Parameter Estimation

The parameter estimation process for ARIMA and smoothing models is described graphically in FigureĀ 53.1.

The specification of smoothing and ARIMA models is described in ChapterĀ 48: 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.
