 Constructs are unobservable or latent factors that are represented by multiple variables.  These equations depict all of the relationships among constructs (the dependent and independent variables) involved in the analysis.  It examines the “structure” of interrelationships expressed in a series of equations, similar to a series of multiple regression equations. is a family of statistical models that seek to explain the relationships among multiple variables simultaneously. WHAT IS SEM Structural Equations Modeling. When the constructs of interest can be measured with limited ambiguity (such as price or weight),there are unique advantages to SEM over linear regression in that SEM allows the creation and estimation of models with multiple dependent variables and their interconnections at the same time (Gefen et al., 2011) Variables are theoretical constructs that cannot be measured directly (such as beliefs, intentions, and feelings) they could only be measured indirectly through those characteristics we attribute to them.

SEM has potential advantages over linear regression models that make SEM a priori the methods of choice in analyzing path diagrams when these involve latent variables with multiple indicators (Gefen et al., 2011).

Contrary to first generation statistical tools such as regression, SEM enables researchers to answer a set of interrelated research questions in by modeling the relationships among multiple independent and dependent constructs simultaneously (Gerbing & Anderson, 1988).Ĭapability for simultaneous analysis differs greatly from most first generation regression models such as linear regression, LOGIT, ANOVA, and MANOVA, which can analyze only one layer of linkages between independent and dependent variables at a time (Gefen et al., 2000, p.3&4).

Structural Equation Modeling (SEM) called as the second generation data analysis techniques (Bagozzi & Fornell, 1982).

Why we prefer SEM as a second generation analysis technique to first generation? Īssessment of measurement model and Structural model.
