| Tiivistelmä: | Forecasting methods are very important in decision making process. Combining extrapolation (or naive) models is an alternative to using any one model. This method has shown promise for improving forecasting accuracy at reasonable additional cost. Previous combination modeling can be extended by selectively including models in combination rather than using all individual models in a set. There are evaluated six new model combinations, investigated the impact of forecasting time horizon, and investigated alternative error measures to mean square error. Results support using a model combination that selects the best 3 to 5 models from the 10 models studied. |
