How to compare models of dependent samples

Questions about the implementation and application of the PLS-SEM method, that are not related to the usage of the SmartPLS software.

How to compare models of dependent samples

Post by Mari »

After googling with rather limited success I hope for a hint here:
I want to make an analysis that is analogous to a Multigroup Comparison. The difference is that I distinguish not between groups but want to compare models for 2 different dependent variables, where the data was collected on the same particiants thus making the samples dependent.
Concretely, I built two compositionally aquivalent models to predict 2 different types of behavior and want to test if the path coefficients differ. Given the data was collected on the same people the models are not independent of each other, thus I wonder how I would adequately test if differences between the path coefficients for model 1 and model 2 are significant?


Thanks a lot!

There is a nice article on how to conduct difference test between individual parameters in a model in PLS: Rodríguez-Entrena, M., Schuberth, F., & Gelhard, C. (2016). Assessing statistical differences between parameters estimates in Partial Least Squares path modeling. Quality & Quantity, 1-13.

Thanks a lot!
Dear Mari,
As the Dr. Becker pointed out, the following paper can help to solve your issue: Assessing statistical differences between parameters estimates in Partial Least Squares path modeling. The good news is that a couple of Excel sheets are available upon request to the authors.
Best regards

Even I have the same issue.
I have to compare two different models on smart pls.
Can I compare on the basis of tvalues?
