Plotting aids for multivariate calibration and chemostatistics

Abstract Spiegelman, C.H., 1992. Plotting aids for multivariate calibration and chemostatistics. Chemometrics and Intelligent Laboratory Systems , 15: 29–38. There are few published procedures for plotting multivariate calibration data. In this paper I give some new plotting techniques that have been useful in my research and consulting. There are plots for detecting matrix effects, and other violations of Beer's law, plots for checking the selectivity of channels and frequencies, and plots that help diagnose the importance of frequencies within a peak.
