摘要

结构方程建模(SEM)代表了一种用于指定和评估因果网络假设的定量方法。SEM的应用通常涉及使用专门的软件包,这些软件包可以实现估计程序、自动化模型检查和汇总结果的输出。有时,研究人员希望实现的用于表示其数据关系的规范细节不受可用SEM包的支持。在这种情况下,可能需要使用专门的回归工具“手工”开发和评估SE模型。在本文中,我展示了一种定制SEM应用的通用方法。所示方法可用于SE模型中非线性、多级和其他自定义规范的广泛专业应用。

General guidance for custom-built structural equation models
Structural Equation Modelling (SEM) represents a quantitative methodology for specifying and evaluating causal network hypotheses. The application of SEM typically involves the use of specialised software packages that implement estimation procedures and automate model checking and the output of summary results. There are times when the specification details an investigator wishes to implement to represent their data relationships are not supported by available SEM packages. In such cases, it may be desirable to develop and evaluate SE models “by hand”, using specialised regression tools. In this paper, I demonstrate a general approach to custom-built applications of SEM. The approach illustrated can be used for a wide array of specialised applications of non-linear, multi-level and other custom specifications in SE models.
