gasoline
(Package: pls) :
Octane numbers and NIR spectra of gasoline
A data set with NIR spectra and octane numbers of 60 gasoline samples. The NIR spectra were measured using diffuse reflectance as log(1/R) from 900 nm to 1700 nm in 2 nm intervals, giving 401 wavelengths. Many thanks to John H. Kalivas.
oliveoil
(Package: pls) :
Sensory and physico-chemical data of olive oils
A data set with scores on 6 attributes from a sensory panel and measurements of 5 physico-chemical quality parameters on 16 olive oil samples. The first five oils are Greek, the next five are Italian and the last six are Spanish.
mayonnaise
(Package: pls) :
NIR measurements and oil types of mayonnaise
Raw NIR measurements (351 wavelengths, 1100-2500 nm in steps of 4 nm) taken on 54 samples of mayonnaise based on six different oil types (soybean, sunflower, canola, olive, corn, and grapeseed). The resulting 54 samples were measured in triplicates, resulting in 54 x 3 = 162 different spectra (120/42 training/test).
yarn
(Package: pls) :
NIR spectra and density measurements of PET yarns
A training set consisting of 21 NIR spectra of PET yarns, measured at 268 wavelengths, and 21 corresponding densities. A test set of 7 samples is also provided. Many thanks to Erik Swierenga.
