Selection of Samples for Calibration in Near-Infrared Spectroscopy. Part II: Selection Based on Spectral Measurements

Volume 44, Number 7 (Aug. 1990) Page 1152-1158

Isaksson, Tomas; Næs, Tormod


Two strategies for selection of samples based on spectral measurements on a large set of samples are tested and compared. A method based on cluster analysis appears to be the best. The same prediction results achieved with the whole calibration set of 114 samples were obtained with only 20 samples selected by this algorithm.
