Factor-based SEM
There has been a long and in some instances fairly antagonistic debate among proponents and detractors of the use of Wold’s original partial least squares (PLS) algorithms in the context of structural equation modeling (SEM). This debate has been fueled by one key issue: Wold’s original PLS algorithms do not deal with actual factors, as covariance-based SEM algorithms do; but with composites, which are exact linear combinations of indicators. The factor-based SEM algorithms in WarpPLS have been developed specifically to address this perceived limitation of Wold’s original PLS algorithms.

What's the difference between CFM3 - CFM2 and CFM1? CFM1 appears to show quite adequate validity and reliability while CFM2 is a little bit less. However, CFM3 shows much less validity and reliability.
Thank you in advance
Hi Anon. The differences are discussed on page 32 of:
