numbers of spectra.

Method
Monte Carlo
Random

this selection is suggested where there is only one spectrum for each substance
was measured but is not recommended (measurement mistake is not clear). 3
measured spectra of the same sample could be separated.

Sequence

e.g. 70% of the spectra are selected automatically. The measured spectra will
be separated time dependent.
3 measured spectra of the same sample can be separated.

Blockwise

to distribute 2/3 of all measured spectra into the calibration set, 6 spectra are
selected to the C-Set and 3 left out for V-Set in the range from 1 to the last
measured spectra. This is the most common selection method.

Custom
(Spectra)

user selected by spectrum number. To separate two spectra blocks, a comma
