隐变量交互作用分析建模方法——两阶段最小二乘法(2SLS)及其在SAS软件上的实现

Modeling Latent Variable Interaction Effect Analysis——2SLS and its Realization by SAS Software

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.
