摘要
在现有文献研究的基础上，对组合预测模型中权系数的估计问题作了进一步研究，给出了两种估计方法，即最小平方法和最小方差法。讨论了权系数的约束条件和组合预测效果评价问题。
On the basis of the analysis of present data, this paper does a further study on the estimation of weight coefficients of combination forecast model. Two methods of estimation weight coefficients have been put forward. They are the methods of the least square and the least variance. It discusses the binding conditions of weight coefficients and the effect evaluation of combination forecast model.
