Quantitative quick view (Soy meal analyzed in transmitance)

During this tutorial about the analysis of Soy meal in transmitance with an Infratec, we will see also the quantitative analysis, once we have seen the spectra characteristics.
This is just a quick look to a quantitative analysis to see where the extreme spectra samples appear in the XY plots of the quantitative analysis.
As we can see in some of the plots appear the sample "298" as an outlier (specially in Moisture). There are clearly chemical outliers with a high residual, due probably, to a mistake in the lab value.
Soy meal is normally analyzed by NIR instruments and not by NIT instruments, but we will continue with this work to see what statistics we can obtain from the equations and from a validation.
