Techniques of Parameter Estimation in Harmonic Means Combining Forecasts
摘要
本文从几何距离角度出发，研究调和平均组合预测中的参数估计技术，提出三种确定组合预测权系数的新方法。理论分析和预测实例表明，新的组合预测参数估计技术行之有效。 This paper studies the techniques of parameter estimation in harmonic means combining Forecasts at the angle of geometric distance.Three new techniques of determining the combining weights are proposed.Theoretical analysis and Forecasting examples all show that the new techniques are Feasible and eFFective.
