                  Total set  :        295:        295:        295:       85:   28.8
               Training set  :         72:         76:      74.00:       20:   27.0
     Invisible training set  :         74:         71:      72.50:       16:   22.1
            Calibration set  :         74:         74:      74.00:       23:   31.1
             Validation set  :         75:         74:      74.50:       26:   34.9

The column "first": how many compounds in the training set,
in the invisible training set, in the calibration set
and in the validation set, for the first split

The column "second": how many compounds in the training set,
in the invisible training set, in the calibration set
and in the validation set, for the second split

The column "Naverage" means (N1+N2) / 2,
where N1 and N2 are the number of compounds which are distributed into X,
for split 1 and split 2; X can be (i) training set; (ii) invisible training set;
(iii) calibration set; and (iv) validation set.

The column "Identical" contains the numbers of compounds which are distributed
into the same set (i.e. training set; ..., validation set) for split 1 and split 2.

The column "Identical (%)" contains the percentage of compounds which are distributed
into the same set (i.e. training set; ..., validation set) for split 1 and split 2.
