协方差结构模型分析中的模型等同问题

The Problem of Equivalent Models in Covariance Structure Analysis

协方差结构模型分析是近年来逐渐流行的统计分析技术。文章主要讨论了应用该技术中出现的模型等同问题。其一，何为等同模型及如何识别某个模型的备择等同模型；其二，以一个实例说明模型等同问题在研究中所造成的影响；其三，如何处理模型等同问题。

Covariance structure model analysis is becoming popular recently. This paper discusses the problem of equivalent models in application of this analysis technique. Firstly,what is an equivalent model and how to discover the alternative equivalent models for a given model;secondly,the impact of equivalent models in research is demonstrated by an example;thirdly,the methods to deal with the problem of equivalent models.
