| Abstract: | A range combined forecasting model is proposed from the points of statistics. Under the condition that forecasting error has norinal distribution the optimal solution of this model is similar to that of combined forecasting model with sum of squares of error and it also has simple calculation.In the end time-variant weights combined forecasting model is discussed. |
