FOREWORD

This book clearly demonstrates Dr. Ken Wong’s expertise in the field of PLS-SEM. His work broadens and strengthens the advanced statistical skills of researchers and practitioners. Readers who are eager to explore this subject would benefit from this refreshing step-by-step guide and be able to elevate their analytical skills. I have thoroughly reviewed this textbook and highly recommend it to the scholars.

PREFACE

Partial Least Squares Structural Equation Modeling (PLS-SEM)¹ is a second-generation multivariate statistical procedure that can be applied in marketing research (Biong & Ulvnes, 2011; Hair, Sarstedt, Ringle, & Mena, 2012; Wong, 2010, 2016). This variance-based SEM method is a great way to estimate complex interrelationships simultaneously and is well-known for its ability to make prediction in success factor studies (Albers, 2010; Rigdon, 2014). PLS-SEM can accommodate both formative² and reflective³ measurement model types. Unlike Jöreskog’s (1973) covariance-based SEM (CB-SEM) that is built upon a common factor model, PLS-SEM follows a composite model approach in construct measures estimation (Lohmöller, 1989). As such, it is great for measuring not only effect indicators⁴ in reflective measuring model, but also composite indicators⁵ in a formative measurement model. With correct specification, PLS-SEM can be used to approximate formative measurement model that consists of causal indicators as well (Sarstedt, Hair, Ringle, Thiele, & Gudergan, 2016).

Researchers have increasingly turned to PLS-SEM for business research (Hair, Sarstedt, Pieper, & Ringle, 2012; Carrion, Henseler, Ringle, & Roldan, 2016) and this statistical procedure has been adopted by science researchers as well (Hsu, Chang, & Lai, 2016; Jisha, & Thomas, 2016; Kansky, Kidds, & Knight, 2016). A wide range of software can be used to perform PLS path modeling (Wong, 2010) but one called SmartPLS (Ringle, Wende, & Becker, 2015) has gained popularity in recent years. Version 3 of this software has introduced new features that help researchers to automatic some statistical procedures that could only be performed manually in the previous versions.

Despite the hard work put forth by PLS-SEM researchers, the amount of literature on these emerging topics is still limited and they have not yet been fully covered by major research textbooks. Many of my Masters, PhD and DBA students still find the existing journal articles and books difficult to comprehend, especially when their dissertation-writing deadlines are fast approaching. To make it worse, some of their supervisors have never dealt with PLS-SEM before, making it even more difficult for these poor students to learn this wonderful data analysis methodology.

This book fills the gap by demonstrating through marketing-related examples how SmartPLS can be used practically in both version 2 and 3 of the software. Advanced techniques such as Confirmatory Tetrad Analysis (CTA-PLS), Quadratic Effect Modeling (QEM), Heterogeneity Modeling, Higher Order Construct Modeling (HCM), Mediation Analysis, and Categorical Moderation Analysis (PLS-MGA) are explained in a step-by-step manner to help researchers master these techniques confidently.

The PLS-SEM field has progressed significantly in the past few years with substantial development of new techniques. For example, we can now obtain better results for reflective models using Consistent PLS (PLSc), assess discriminant validity using Heterotrait-Monotrait Ratio of Correlations (HTMT), contrast total effects using Importance-Performance Matrix Analysis (IPMA), test goodness of model fit using Standardized Root Mean Squared Residual (SRMR), Unweighted Least Squares Discrepancy (dULS) and Geodesic Discrepancy (dG). All of these latest developments have taken PLS-SEM to the next level and are discussed in Chapter 12.

to work along the examples. Regarding the book title, I have chosen to mention 38 hours because that is the duration of my popular PLS-SEM research module. If
