摘要
本文针对传统优选组合在评判指标上存在单一性的缺陷,将多元统计中的因子分析方法引入到多指标的综合评判,从而优选出最佳预测方法,并通过实证分析,说明该方法有较强的自适应性和较高的预测精度。
In view of traditional optimization combination in judgment target unitary existence flaw, tills article introduces the factor analysis method of multivariate statistical to the multi - targets comprehensive judgment, and chooses the optimum prediction method. And through real diagnosis analysis, this method explained has strong auto- adapted and the high forecast precision.
