title: [Application of ridge regression spectrophotometry to the determination of multicomponents in aspirin compound tablet].
abstract: In this paper, a ridge regression method of spectrophotometry in multiwavelength is proposed. The basic principle and computing of this method applied to multicomponent analysis were discussed. This method was applied to simultaneous determination of multicomponents in aspirin compound tablet and satisfactory results were obtained. The experiment clearly indicates that ridge regression may provide a new approach to experimental measurement of multicomponent analysis computations.
