Hi All,
Can anyone help please! I want to calculate a model-based reliability coefficient like composite reliability or Omega total (F/F+E) where f is the total loadings squared and E is the error variance). my model is multidimensional, the first orders are reflective and second and third orders constructs are formative. How can I get a total model-based reliability for this? I tried to calculate it manually but can't find the error variances in the results. I'm new to PLS and more used to CBSEM.
any help will be greatly appreciated.
