Session 1: Introduction to Partial Least Squares – Structural Equation Modeling
(PLS-SEM) Using SmartPLS and WarpPLS software packages

SEM is a statistical approach to analyze a hypothetical framework simultaneously. It allows a researcher to test and develop theories, and to test the relationships between latent variables on the conceptual model. There are two types of SEM; the covariance-based technique (CB-SEM) and the variance-based or partial least squares SEM (PLS-SEM). CB-SEM is confirmatory in nature, whereas PLS-SEM can handle theory development and prediction. The PLS-SEM is a variance-based approach and aims to maximize the explained variance of the dependent latent constructs; whereas the CB-SEM aims to reproduce the theoretical covariance matrix. Therefore the PLS-SEM is preferred when the researcher wants to predict the construct and identify a relationship between them. In addition, PLS-SEM can handle more complex model including formative, composite and reflective constructs. PLS-SEM has been applied in many studies in marketing, business, strategic management, and social science areas in recent years. However, a few numbers of tourism and hospitality researches have used this useful and powerful method. Most of the tourism studies were interested in traditional CB-SEM rather than PLS-SEM. Therefore, a PLS-SEM workshop can be very significant for tourism and hospitality researchers.

Session 2:

Mediator – Moderator Using PLS-SEM; WarpPLS 6.0 and SmartPLS 3.2.7 Software Packages

Many studies in management, psychology, social science, including hospitality and tourism rely on mediating and moderating variables. Mediating variables are behavioral, psychological, or social constructs that transmit the effect of one variable to another variable. Mediation is one way that a researcher can explain the process or mechanism by which one variable affects another. However, moderating variable are those which affect the strength or nature of the relationship between two other variables.

This session aims to explain the concepts and theories behind mediator and moderator and describes various forms of simple and complex meditors, moderators. Different methods to assess mediators and moderators will be discussed in this session. These assessments will be conducted in the context of partial least squares- structural equation modeling (PLS-SEM) using two powerful software packages namely; WarpPLS 6.0 and SmartPLS 3.2.7.
