Variable Selection (PLS_Toolbox option)

See how the statistics can be improved (for this beer data set) with the variable selection option, Normally we tend to use always the full spectra options, but there can be some cases where we can get better statistics for validation with the variable selection options. To do this in a manual way will be a lot of work of trial and error, so an algorithm to find them is really useful.

 

I really like all the plots and figures of this software, and can give some ideas when using R. The software seems to have a lot of chemometrics tools, so it is interesting to look to other videos of this software. You are welcome to give your comments if you use this software.
