Chemometrics II -- Regression and PLS

Course Description

If PCA is the most important chemometric method, then Partial Least Squares (PLS) regression is a very close second. Chemometrics II -- Regression and PLS covers regression methods starting with Classical Least Squares (CLS) and Multiple Linear Regression (MLR) and culminates in Principal Components Regression (PCR) and PLS Regression. Students will learn to safely apply the methods to create predictive models in a variety of applications. The course includes hands-on computer time for participants to work example problems using PLS_Toolbox.

Prerequisites

Linear Algebra for Chemometricians, MATLAB for Chemometricians and Chemometrics I -- PCA, or equivalent experience.
