Keywords: Covariance stabilization ; Linear mixtures ; Cross-validation ; Rank-one updates ; Chemistry ; Analytical Chemistry and Spectroscopy

Topics: Chemistry and Pharmacology

Notes: Some well-established ideas from classical covariance stabilization and shrinkage estimation are extended to the context of physical mixtures through the use of a model developed by Burdick and Rayens. A cross-validation techique is proposed and associated computational issues are addressed. The methodology is evaluated in the context of real polychlorinated biphenyl data.
