| Abstract: | This paper proposes a new algorithm for multivariate calibration named Principal Component Regression Based on Wavelet (PCRW)
which combines wavelet decomposition technique with the factor analysis method for establishing a duplicate denoising mechanism.
A practical example in spectral analysis of a typical multicomponent pharmaceutical system was used to verify the effectiveness
of the algorithm. It was shown that PCRW produced fewer prediction errors than those obtained by using PCR.
