2-Day Workshop on PLS Path Modeling

After a return to the origins of structural equation modeling (SEM), the PLSPM algorithm will be presented. A methodology to interpret results will then be suggested on the basis of real life cases. The training session will be illustrated by applications using XLSTAT.

      • PLS algorithm for computing Latent Variable Scores
    • PLS Algorithm for the case of one and two blocks:
      • Principal Component Analysis, Tucker’s Inter-battery Analysis, Canonical Correlation Analysis, PLS Regression, Redundancy Analysis
