【摘要】 Theil不等系数是一种度量预测精度的另一种相关性指标,将Theil不等系数和IOWHA算子的概念相结合,提出一种新的基于Theil不等系数的IOWHA算子最优组合预测模型,并定义了优性组合预测的概念.利用该模型对税收收入进行了组合预测,结果表明该组合预测方法是可行和有效的,且该模型是一种优性组合预测.更多还原

【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 model.The example shows that the combination forecasting model is effective and reasonable,and it is superior combination forecasting.更多还原
