| Abstract: | Based on forecasting effective measure, some new concepts and combination forecasting model with standard deviate of forecasting accuracy are proposed. Then redundant information is pointed out in the two determining theorems. Finally an example is illustrated to show the effectiveness of determining theorems. |
