摘要：

This paper Investigates the effect of multiplicative scatter correction (MSC) and nonlinear regression based on the first two and three principal components for near-infrared reflectance (NIR) spectroscopy data. The focus will be on llne-arlty/nonlinearity as well as treatment of outliers. The main contribution of the paper is the presentation of and testing of a calbration method based on classification and local least-squares regression. The theory Is Illustrated by three examples from NIR analysis. The local linear calibration outperformed traditional methods In two of the examples. © 1990, American Chemical Society.
