구조방정식 모델링과 이론의 경험적 평가

Structural Equation Modelling and Empirical Evaluation of Theory

Structural Equation Modelling(SEM) serves as a critical role in evaluating a theory. SEM s basic framework and various fit indexes are reviewed in this article. Especially, the conceptual rationale of fit indexes are reviewed. Researcher should assess not only the confirmation/disconfirmation of models but also parsimony of models. Researcher should be careful to select some criteria in evaluating a set of nested models because indexes are based on X² values and factors such as sample size, assumptions regarding the independence of latent variates. and estimation methods may influence the adequacy of performance of X² statistics and fit indexes.
