Webb4 mars 2024 · Therefore, the regression coefficients of X, calculated by using loading and weight vectors, can be the contributions of X to y. This method is called PLS with only the first component (PLSFC). In this study, the contributions of X to y are interpreted with regression coefficients using PLSFC. Webb11 mars 2024 · The coefficient was determined by PLS calculation, and then the regression equation of the dependent variable was constructed.
