  • Classical Least Squares (CLS) Models - Eigenvector Research, Inc.
    ILS methods such as partial least squares PLS are ubiquitous to chemometrics However classical least squares CLS or forward least squares techniques are seeing a resurgence in popularity Two major reasons are better interpretability and the ability to control aspects of the regression modeling As with ILS CLS methods can be used for exploratory analysis detection classification and quantification This half day course will start by covering CLS regression methods including classical extended weighted and generalized least squares It will be shown how these methods can be used to account for interferents i e analytes other than the one of interest in spectroscopic systems CLS also provides a natural framework for the development of popular de cluttering methods such as External Parameter Orthogonalization EPO and Generalized Least Squares GLS weighting The course includes hands on computer time to work through example problems It will also be shown how constraints can be easily employed with these methods to allow greater control over the modeling Prerequisites Linear Algebra for Chemometricians MATLAB for Chemometricians Chemometrics I PCA and Chemometrics II Regression and PLS or equivalent experience Course Outline 1 0 Introduction 1 1 The CLS Model 1 2 Inherent Challenges 2 0 Practical

  • Multi-block and Multi-set Methods - Eigenvector Research, Inc.
    which case the multi block variants of PCA and PLS may be appropriate Another case is when the data is semi batch such as where processes are run for periods of time and then reset e g when catalysts are regenerated or the process equipment is cleaned In these cases tools such as Simultaneous Components Analysis SCA or Multi level SCA MLSCA may be used to understand the difference between runs and the variation within runs Multi level PLS variants are also potentially useful Finally instances where data sets consisting of blocks with different numbers of modes must be fused are considered For example a 3 way data set might share a mode with a 2 way data set such as when a number of batch data records must be related to multiple quality parameters In these instances models based on coupled matrix and tensor factorizations CMTF may be applied The course includes hands on computer time using MATLAB and PLS Toolbox for participants to understand better the differences between the various options Prerequisites Linear Algebra for Chemometricians MATLAB for Chemometricians Chemometrics I PCA and Chemometrics II Regression and PLS or equivalent experience Introduction to Multi way Analysis maybe also
