| Abstract: | It is aimed to demonstrate how multivariate forecasting models can be effectively used to generate high performance forecasts for typical business applications. The forecasts generated by a simultaneous transfer function model and a white noise regression model are compared with that of a univariate ARIMA model. The accuracy of these forecasting models is judged. It is found that ignoring the residual serial correlation can greatly degrade the forecasting performance of a multivariable model, and in some cases, cause a multivariable model to perform inferior to a univariate ARIMA model. |
