public class ARAutoUnivariateEx2
extends Object

Finds the minimum AIC autoregressive model for the Canadian lynx data.

Using the Canadian Lynx data included in TIMSAC-78, ARAutoUnivariate is used to find the minimum AIC autoregressive model using a maximum number of lags of maxlag=20.

This example compares the three different methods for estimating the autoregressive coefficients, and it illustrates the relationship between these estimates and those calculated within the TIMSAC UNIMAR code. As illustrated, the UNIMAR code estimates the coefficients and innovation variance using only the last \(N\)-maxlag values in the time series. The other estimation methods use all \(N-k\) values, where \(k\) is the number of lags with minimum AIC selected by ARAutoUnivariate.

This example also illustrates how to generate forecasts for the observed series values and beyond by setting the backward origin for the forecasts.
