基于预测有效度的组合预测方法冗余信息的判定
Determining Theorems of Redundant Information about Combination Forecasting Model Based on Forecasting Effective Measure
【摘要】 基于预测方法有效度的概念 ,建立了考虑预测精度标准差的预测有效度的组合模型 ,提出了几个新的概念 ,给出冗余信息出现的两个判定定理 .并用实例说明判定定理的有效性 .
【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.
