Working these days with the tecator data set traying to find the better statistics as possible for the cross validation, and checking after with the test set. I use algorithms to remove the scatter but at the moment not derivatives to enhance the resolution. I show the statistics results for the CV and the validation results for the test set.
Multiple Scatter Correction has at the moment the better statistics for protein, but still some combinations of Math treatments could be tryed.
This is the XY plot for the test set with the pls model using the train set math treated with MSC.
