Transparent PLS-SEM Estimation for Composite-Based Reflective Models // A transparent and modular implementation of Partial Least Squares Structural Equation Modeling (PLS-SEM) focused on reflective measurement models (Mode A). The package separates estimation, bootstrap inference, and predictive evaluation into independent components, emphasising algorithmic transparency, reproducibility, and researcher-controlled analysis. Methods are based on Tenenhaus, Esposito Vinzi, Chatelin Lauro (2005) doi:10.1016/j.csda.2004.03.005, Hair, Risher, Sarstedt Ringle (2019) doi:10.1108/EBR-11-2018-0203, and Henseler, Ringle Sarstedt (2015) doi:10.1007/s11747-014-0403-8.
