| Abstract: | The Theil coefficient is a new kind of correlations.We study the properties of harmonic means combination forecasting method based on Theil coefficient to demonstrate the effectiveness of this method theoretically,such as superior combination forecasting and dominant forecasting method etc,the existence of noninferior combination forecasting,superior combination forecasting and redundant forecasting method are discussed.Finally redundant information is given in the determining theorem. |
