| Abstract: | In
equation of multivariate linear regression the item of residue includes various errors. It
can be regress anain and other regression coefficients can be get. With the sum of
regression coefficent of two-time regression a improved model can be build. In
quantitative analysis of Near-Infrared spectra the prediction result of new model is
better than the original one. |
