PLS_Toolbox

The by Eigenvector Research is the industry-standard software suite for chemometrics and multivariate data analysis within MATLAB. It provides both a graphical user interface (GUI) for point-and-click analysis and a command-line interface for custom scripting and automation. Core Capabilities

• number of components (A) via repeated K-fold CV,
• sparsity level (λ) via nested CV or information criterion,
• optional scaling/centering and handling of missing data (EM-imputation).
