Dear Professor Bido: Thank you for the references. However, I was more looking for actual proof that studies testing for mediation in PLS got accepted in marketing or IB journals. A method can be correct and adequate for a study, however if it does not get applied and accepted/published by well know...

Estimating Mediation Effects using PLS - Can('t) you?

Dear PLS users: I saw that SmartPLS users talk about and test for mediation effects in their models. The following search on EBSCO Host did not return one article: "marketing" and "partial least squares" and "latent variable" and "mediation" . Is there any sou...

Dear Bido: Thank you so much for clarifying this issue. I could not find the answer in the literature. Even in Koeske & Koeske (2006) where the authors describe a large number of different mediation/suppression scenarios, the exact case I am facing is not described. Now I know that strictly stic...

Signs in Interaction Effects

Hello everyone: I am testing interaction effects and came across a constellation of path coefficients I am not sure about how to interpret. The original model (without mediator) has a negative beta for A -> B. When I model C as a mediator beta A -> B is still negative but slightly more negative than...

Changing Signs of Factor Loadings

Hi all: I came across an effect that I don’t know how to interpret. Depending on where I put paths between LVs in my model, my factor loadings change. I tested all the constructs, using CFA and established reliability and validity before I started modelling in SmartPLS. Also the factor loadings of a...
