| Abstract: | Weighted geometric means combination forecasting is a kind of nonlinear forecasting method. On the basis of traditional combination forecasting model, a new weighted geometric means combination forecasting model based on L_1 norm is constructed. The conception of superior combination forecasting is proposed in this paper. Its solutions of the combination forecasting model are attributed to a linear programming model. Finally this combination forecasting model is illustrated to be superior combination forecasting, which shows that this model is effective. |
