Pls regression method
WebbPLSRegression is also known as PLS1 (single targets) and PLS2 (multiple targets). Much like Lasso , PLSRegression is a form of regularized linear regression where the number of components controls the strength of the regularization. 1.8.4. Canonical Correlation Analysis ¶ Canonical Correlation Analysis was developed prior and independently to PLS. Webb4 mars 2024 · A regression coefficient of one component can be used as the contribution of the component to y because there is only one component in PLS. 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).
