SEM在文献中有许多同义词和特殊情况,包括路径分析(path analysis)、因果建模(causal modeling)和协方差结构分析。 SEM涉及的两个模型: SEM涉及两个模型的评估:测量模型(measurement model)和路径模型(path model)。 路径模型 路径分析是对多重回归的一种扩展方法,它通过同时估计多个多重回归模型或方程,更有效地直接建...
结构方程模型（Structural Equation Modeling，SEM）结构方程模型（Structural Equation Modeling，SEM）是一种多变量统计分析技术，用于分析变量之间的复杂关系。它结合了因子分析和多变量回归分析，允许研究者同时考察多个因果关系。一、基本概念 1. 测量模型（Measurement Model）：测量模型关注的是观测变量（可以直接测量的...
Structural equation modeling (SEM) is a multivariate statistical framework that is used to model complex relationships between directly and indirectly observed (latent) variables. SEM is a general framework that involves simultaneously solving systems of linear equations and encompasses other techniques such...
Example 1: Survival modelLet's do a survival model combined with CFA (confirmatory factor analysis). CFAs model the level of a latent trait using observable measurements.We analyze survival times of nursing home residents. We have censored data; thankfully, not all the residents have died yet...
For example, a theory may suggest that certain mental traits do not affect other traits and that certain variables do not load on certain factors, and that structural equation modeling can be used to test the theory. (A mental trait is a habitual pattern of behavior, thought and emotion.) ...

Numerous examples of applications are given and attention is paid to the underlying philosophy of structural equation modeling and to writing up results from structural equation modeling analyses.doi:10.2307/2988418Murray D. SmithR. H. HoyleJournal of the Royal Statistical Society Series D (The ...
Structural equation modeling(SEM) is a multivariate, hypothesis-driven technique that is based on a structural model representing a hypothesis about thecausal relationsamongseveral variables. In the context of fMRI, for example, these variables are the measured blood oxygen level-dependent (BOLD) time...
