Study of near Infrared Chemometric Models with Low Heterogeneity Films: The Role of Optical Sampling and Spectral Preprocessing on Partial Least Squares Errors
Contributor(s):: Ortega-Zuñiga, Carlos, Reyes-Maldonado, Kerimar, Méndez, Rafael, Romañach, Rodolfo J.
This study is focused on understanding absorption and scattering effects and their impact on the errors observed in near infrared calibration models developed using partial least squares regression able to predict the number of polypropylene film layers stacked together. The films provided a...
