Gray Classical Least Squares (CLS) with GLSW filter

PLS_Toolbox and Solo 9.0 include the ability to make Gray Classical Least Squares (CLS) models. This is a CLS model that uses Generalized Least Squares Weighting (GLSW) or External Parameter Orthogonalization (EPO) filter data based on the residuals of a preliminary CLS model. This video shows how to use this functionality in the new PLS_Toolbox and Solo.
