Second Order construct

Post by mohamed » Fri Oct 19, 2018 4:56 pm

Hello Everyone,
I want to ask you about the best approach to use in constructing the second order construct in PLS. As there are two methods (the repeated-indicator approach) and the (Two-Stage approach). Actually, I know that the repeated-indicator measure works best when the number of indicators of latent variables are equal. In my case, the indicators of every latent variable is not equal and this why i am confused and i don't know which is better and whether the differences in the results will be higher or not regarding the two methods. my model is also reflective for first-order and second-order constructs.
