October 8, 2020


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

Eigenvector Research, Inc. is pleased to bring you Variable Selection, an online instructor-led live short course. Complete information about the course can be found by following the links below.

Course Description

Variable Selection deals with one of the most difficult problems in chemometrics, selecting variables for regression and classification. In many situations in model building, variable selection, is useful for improving predictions, or for minimizing the number of variables and for other purposes such as reducing costs. But how to do it? Genetic algorithms, forward selection, and jack-knifing are just few of the possible ways to do variable selection. In this short course, the theory behind when to use what is given and an outline of different possible approaches is given. Through examples and exercises, it is shown how some approaches work well in some situations and not in others.The course includes hands-on computer time for participants to work example problems using PLS_Toolbox or Solo.

Prerequisites

Chemometrics II: Regression and PLS or equivalent experience.
