| Abstract: | The Theil coefficient is another kind of index which can be used to measure the forecasting precision.In this paper,a new combination forecasting model is proposed based on the Theil coefficient and induced ordered weighted harmonic averaging(IOWHA) operator by combining the induced ordered weighted harmonic averaging(IOWHA) operator and the Theil coefficient.In the meantime,the conception of superior combination forecasting is given. Finally,combination forecasting of tax revenue is given by using this mod... |
