Fluorescence spectra were measured on sugar dissolved in water. The according
quality parameter color was determined in a sugar plant laboratory. In
order to avoid the laborious determination of color in the laboratory it
would be beneficial to be able to predict color, e.g. from on-line or at-line
measured fluorescence spectra.
Purpose: Using different calibration tools and comparing their relative efficiency. Information: R. Bro, Multi-way calibration. Multi-linear PLS, J. Chemom., 1996, 10(1), 47-62. Prerequisites: Be sure to understand the basics of handling multi-way arrays in MATLAB (Chapter 1). You should know your two-way PLS and PCR |
Use PCA or PARAFAC to investigate if there are any signs of outliers (do not remove any, but bear them in mind in the subsequent calibration modeling step).
