iToolbox for MATLAB^TM

by

Lars Nørgaard

Introduction

The iToolbox is for exploratory investigations of data sets with many collinear variables, e.g. spectral data sets. The main methods in the iToolbox are interval PLS (iPLS), backward interval PLS (biPLS), moving window PLS (mwPLS), synergy interval PLS (siPLS) and interval PCA (iPCA). The application of the methods are described in a manual and demo's for all methods are included in the toolbox.

• Manual (PDF)

The iToolbox for MATLAB is freely available
