Nettet1. jul. 2002 · Combined forecasts from a linear and a nonlinear model are investigated for time series with possibly nonlinear characteristics. The forecasts are combined by a constant coefficient regression method as well as a time varying method. The time varying method allows for a locally (non)linear modeling. The methods are applied to three … Nettet14. jul. 2016 · In Jennrich (1969) the model is considered, where x ( n) is a sequence of i.i.d.
