PLS is just a method to reduce variability and number of factors. But EFA and CFA work with SEM. Instead PLS is rather an alternative technique for non parametric data.
EFA is a technique used to reduce the number of factors. Both CFA and EFA are used in SEM analysis, especially CB-SEM because this method uses common variability to measure the constructs. PLS-SEM treats constructs as composites and thus it calculates an index (puntuation) for their measurement. This is way, EFA is not used in PLS-SEM analysis. Both CFA and CB-SEM are used to validate theories. PLS-SEM is used instead for prediction and, therefore, CFA is not used together with this SEM method.
Vasilica Maria Margalina Thank you very much, Professor. It is very clear to me now.
Hope to connect with you in Linked In.
