Introduction Research in science and engineering … Partial Least square regression is a dimension reduction technique used when working high dimension data. Partial least squares (PLS) (also known as projection to latent structure) is a popular method for modeling industrial applications. PLSmit SEM ist - eine Methode, die darauf abzielt, die erklärte Varianz abhängiger Konstrukte im Pfadmodell zu maximieren. K�BT�g��p�s %���� Partial Least Squares is a family of regression based methods designed for the an- ysis of high dimensional data in a low-structure environment. Pages 23-46.

An appendix describes the experimentalPLSprocedureofSAS/STAT software. Partial least squares regression (PLS regression) is a statistical method that bears some relation to principal components regression; instead of finding hyperplanes of maximum variance between the response and independent variables, it finds a linear regression model by projecting the predicted variables and the observable variables to a new space.

The procedure is most helpful when there are many factors and the primary goal is prediction of the response variables. Associations between high-dimensional datasets, each comprising many features, can be discovered through multivariate statistical methods, like Canonical Correlation Analysis (CCA) or Partial Least Squares (PLS). 97‐114 • Abdi, “Partial least squares regression and projection on latent structure regression CCA and PLS are widely used methods which reveal which features carry the association. Partial Least Squares Regression Randall D. Tobias, SAS Institute Inc., Cary, NC Abstract Partial least squares is a popular method for soft modelling in industrial applications.
