Just to clarify: If the model includes constructs that are measured through formative indicators, a statistical ex-post identification of common method bias is not possible with PLS. For explanation see page 900 of Podsakoff, P. M., MacKenzie, S. B., Lee, J.-Y., & Podsakoff, N. P. (2003) . Common me...

Dear Prof. Bido, I face some multicollinearity in my formative measurement models (VIF between 1 and 3 for each indicator). I wanted to apply your approach to conduct a principal component analysis in SPSS to combine the correlating indicators. You mentioned that you should then use the factor score...

Hi, I would like to rewake the discussion. I also have negative weights for my formative indicators. I switched the direction of the arrows in the formative measurement model in SmartPLS as suggested above. However... 1. Not all negative weights disappear 2. The values of the latent constructs are q...

Hi, In my research I try to identify project management success factors that influence the behavior of the customer. The problem in my current research is that I cannot measure any facts from past industry projects, as these projects went terrible wrong or are long time ago. Addtionally my total ind...

Literature on how to develop questions to measure SEM?

Dear all, Usually when measuring indicators with questions in a survey researches tend to use questions/scales from existing publications. In my case there is no similar measurement in literature. Thus, I have to develop questions (and scales) by myself. There are a lot of books and articles on how ...

CSF: How to measure endogeneous variable?

Dear all, I am about to define mit model to test with PLS. From literature I've collected around 40 critical success factors (CSF) that load on (are grouped in) different exogeneous latent variables. Each success factor will be reflected by one question in the questionnaire (using Likert-scales for ...
