Calibração multivariada para sistemas com bandas sobrepostas através da análise da fatores do tipo Q Q mode factor multivariate calibration for systems with overlapped bands
<abstract language="eng">A multivariate calibration method to determine chemical compositions of systems with severely overlapped bands is proposed. Q mode factors are determined from the spectral data and subsequently rotated using the varimax and oblique transformation of Imbrie. T...
