This tutorial will help you set up and interpret a PartialLeastSquaresDiscriminantAnalysis in Excel using the XLSTAT software. Not sure this is th The predominance of partialleastsquares-discriminantanalysis (PLS-DA) used to analyze metabolomics datasets (indeed, it is the most well-known tool to perform classification and regression in metabolomics), can be said to have led to the point that not all researchers are fully aware of alternative multivariate classification algorithms. Partialleastsquaresdiscriminantanalysis (PLS-DA) is an adaptation of PLS regression methods to the problem of supervised1 clustering. It has seen extensive use in the analysis of multivariate datasets, such as that derived from NMR-based metabolomics. Partialleastsquaresdiscriminantanalysis: taking PLS-DA using one partialleastsquares optimisation and validation issues – A tutorial, Analytica An Introduction to PartialLeastSquares Regression Randall D. Tobias, SAS Institute Inc., Cary, NC Abstract Partialleastsquares is a popular method for soft PartialLeast-Squares and DiscriminantAnalysis.
