H2: What is Structural Equation Modeling? What is Structural Equation Modeling?
Structural equation modeling (SEM) is a label for a diverse set of methods used by scientists in both experimental and observational research across various disciplines, such as social sciences, behavioral sciences, business, education, medicine, and environmental sciences. SEM is used to test hypotheses about causal relationships among variables that are not directly observable, but are inferred from other variables that are measured. SEM involves two main components: a measurement model and a structural model. The measurement model specifies how the observed variables (also called indicators or manifest variables) are related to the latent variables (also called constructs or factors). The structural model specifies how the latent variables are related to each other, as well as to any exogenous variables (variables that are not influenced by other variables in the model). The measurement model and the structural model can be combined into a path diagram, which is a graphical representation of the hypothesized relationships among all variables in the model. SEM allows researchers to test complex theories that involve multiple variables, mediators, moderators, interactions, nonlinear effects, feedback loops, etc., as well as to assess the validity and reliability of their measurements. SEM also provides various fit indices that indicate how well the model matches the data, as well as various statistics that can be used to test the significance and effect size of the relationships.
SEM is a powerful and flexible tool for data analysis, but it also requires a lot of knowledge and skills to use it properly. You need to have a clear theoretical framework, a good understanding of the assumptions and limitations of SEM, and a suitable software to perform the analysis. This is where Lisrel 8.8 comes in handy. Why Use Lisrel 8.8 for SEM?
