报告摘要

Partial-least-squares structural equation modeling, its properties and applications

Structural equation modeling (SEM) is a widely used technique for studies involving latent constructs. While covariance-based SEM (CB-SEM) permits estimating the regression relationship among latent constructs, the parameters governing this relationship do not apply to that among the scored values of the constructs, which are needed for prediction, classification and/or diagnosis of individuals/participants. In contrast, the partial-least squares approach to SEM (PLS-SEM) first obtains weighted composites for each case and then estimates the structural relationship among the composites. Consequently, PLS-SEM is a preferred method in predicting and/or classifying individuals. In this talk, I will (1) introduce PLS-SEM methodology, (2) discuss its statistical and psychometric properties, (3) issues in its applications with real data, and (4) recent developments.
