WebbContents Summary Partial least squares (PLS) is a method for constructing predictive models when there are many highly collinear factors. This tutorial will start with the spectral data of some samples to determine the amounts of three compounds present. The data includes: Data of the spectra emission intensities at different wavelength (v1 - v43) WebbPartial least squares discriminant analysis (PLS-DA) is a variant used when the Y is categorical. PLS is used to find the fundamental relations between 2 matrices ( X and Y ), i.e. a latent variable approach to modeling the covariance structures in these two spaces. A PLS model will try to find the multidimensional direction in the X space that ... WebbArtificial neural networks (ANN) and partial least squares (PLS) calibration strategies exploiting spectral feature selection were developed and their analytical performance evaluated. The model regression coefficients were 0.990, 1.000, 1.000, and 0.973 for Zn, Cu, Fe, and Mg respectively for ANN and 0.960, 0.985, 0.986, and 0.993 for PLS. charles m fischman md
