New publication on research methodology

“The shortcomings of equal weights estimation and the composite equivalence index in PLS-SEM” is published in the European Journal of Marketing. Authored by Joe F. Hair (University of South Alabama), Pratyush N. Sharma (University of Alabama), Marko Sarstedt LMU Munich), Christian M. Ringle (Hamburg University of Technology), and Benjamin D. Liengaard (Aarhus University), the paper critically discusses the use of equal indicator weights in construct measurement.

We find that equal weights suffer from a series of limitations and lag behind differential weights estimated via partial least squares structural equation modeling.

The paper is open access and can be downloaded.
