目的:探讨隐变量交互作用分析的建模方法及其在SAS软件上的实现。方法:阐述隐变量交互作用分析建模的原理,并拟合一个隐变量交互作用分析示例。结果:示例中交互作用项产生的交互效应不容忽视。结论:在应用结构方程模型分析隐变量产生的效应时,有时候不进行隐变量交互作用的分析可能会产生偏倚。
Objective: exploring the method of modeling latent variable interaction effect analysis in structural equation modeling and the technique of latent variable interaction effect analysis by SAS software.Methods: explicating the basic theory of modeling latent variable interaction effect analysis in structural equation modeling,then demonstrating an artificial example of latent variable interaction effect analysis.Results: the given example showed that the interaction term could not ignored.Conclusion: It may give rise to bias not to complement interaction effect analysis in SEM.
