Abstract:A modified factor analysis method called :nonzero intercept target rotation method is proposed for multicomponent analysis The. influences of, varibles on the results are discussed, The number of wavelengths and their positions are quite important to the calculated precisions. The new criteria are used to select the number of wavelengths and their positions. This method is used to quantitative analysis of the mixture of pigments. For the pigment mixtures of three and five components, the average percentage error is 0.6% and 1.64% respectively.
Keywords:Factor analysis  Nonzero intercept  Pigments
