摘要
因素分析中的连环替代法假定性地将多因素共变影响值归于个别因素,以致分析结果不合理和不同替代顺序得出不同结果。综合替代法试图将共变影响值平分给各有关因素,但其计算过程极为复杂,容易出错和误差。本文通过理论推导和例证分析,揭示综合替代法的计算规律和本质特征,从而有利于综合替代法的电算化,并且基于合理而简便的思路,提出了“权数替代法”,克服了综合替代法的局限性问题。
In order to improve the limitations of chain substitution, people assign equally the commoneffect to evety factor with synthetical substitution (SS), which computing process is very complex andeasy to make mistakes and computing error. By means of the theory derivation and example analyses,this paper reveals the regUlar pattern and the innate character of SS. So it become easy to use thecomputer to calculate its problem. In this paper, also advance a new method--Weighted Substitution,which can overcome the shortcomings of SS.
