New publication on PLS-SEM

05.02.2018 - The article titled "Heuristics versus statistics in discriminant validity testing: A comparison of four procedures,“ authored by George Franke (University of Alabama) and Marko Sarstedt has been accepted for publication in Internet Research, a leading journal in the management information systems field (impact factor: 2.93). This study reviews and extends recent simulation studies on discriminant validity measures, contrasting the use of cutoff values (i.e., heuristics) with inferential tests. Based on a simulation study, which considers different construct correlations, sample sizes, numbers of indicators, and loading patterns, the study assesses each criterion’s sensitivity to type I and type II errors. The findings provide further evidence for the robustness of the heterotrait-monotrait ratio of correlations (HTMT) criterion as an estimator of disattenuated (perfectly reliable) correlations between constructs, whose performance parallels that of the standard constrained Phi approach. Furthermore, the study dentify situations in which both methods fail and suggest an alternative criterion.

Two New Publications on PLS-SEM

29.11.2017 -  Two papers on the use of partial least squares structural equation modeling (PLS-SEM) in hospitality management and human resource management have recently been accepted for publication. In both papers, the authors critically review the use of the PLS-SEM in the corresponding fields, derive guidelines for the method’s use in future studies, and offer recommendations for future research on the method. The first paper will appear in International Journal of Contemporary Hospitality Management, which is the leading journal in the field with an Impact Factor of 3,196. The second paper will be published in International Journal of Human Resource Management, a premier journal in the field with an Impact Factor of 1,65.
