In the Sample menu, apart to see the spectra we have the option to inspect the samples in a principal components space looking for GH outliers. In this case after changing the default configuration by the one I choose in the previous videos I decide to remove the samples with a GH higher tha 4.00.
These samples are marked as spectral outliers, and we can see them in red color merged with the rest of the spectra, so we can inspect possible reason for those GH values.
We can recalculate the PCs again once these samples are remove, but we will do that in the Model Menu in next videos. This time the idea was to remove what we can consider clear spectral outliers.
In the sample menu we have the option to run PLS to have an idea about how the calibration will work and to check if we have clear reference outliers, taht in the case that the values are not correctly typed we can edit them and change to the correct value.
PCA and PLS will be treated specially in the Models menu, where we use the validation set and we will get the performance statistics in the case of PLS or MPLS Models.
