Example: LIBS spectra. For comparison purposes, I used the LIBS spectra of plant materials to predict the concentration of potassium using the PLS and OPLS approaches.

WebbThe PLSRegression calculates the leverage of each point in the latent variable space. We thus do primarily see if a sample has a significant influence on the model in the latent variable space. The leverage does not show directly, how big the influence of the samples was for obtaining the direction of the latent variables. WebbThe equation of the PLS regression model writes: Y = ThC’h + Eh = XWh*C’h + Eh = XWh (P’hWh)-1 C’h + Eh where Y is the matrix of the dependent variables, X is the matrix of the explanatory variables. Th, Ch, W*h , Wh and Ph, are the matrices generated by the PLS algorithm, and Eh is the matrix of the residuals.
