Chemometrics II: Regression and Partial Least Squares

February 23, 2021 - February 24, 2021

The recorded version of this course is now available in our EigenU Recorded Courses area.

Eigenvector Research, Inc. is pleased to bring you Chemometrics II: Regression and Partial Least Squares (PLS), an online instructor-led live short course. Complete information about the course can be found by following the links below.

Course Description

If PCA is the most important chemometric and machine learning 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 or Solo.


Linear Algebra for Chemometricians and Chemometrics I: PCA or equivalent experience. MATLAB for Chemometricians may also be helpful.
