A Comparison of Graphical Models and Structural Equation Models for the Analysis of Longitudinal Survey Data
[chapter]
Methodology of Longitudinal Surveys
Graphical chain modelling (GCM) and structural equation modelling (SEM) are two approaches to modelling longitudinal data. Both approaches have their origins in path analysis and provide pictorial representations of the association between variables, which are usually ordered temporally. Both methods also aim to identify the direct and indirect effects of one variable on another. While the SEM approach specifies a single model for the complete system of variables being studied, the GCM approach
