  1. The coefficient of determination (R2) and the C(p) were calculated in the training set, while the root mean square error (RMSE) was estimated in the validation set. The multivariate models were significant at 5% of probability or less
  2. Bold values indicate the parameters of the statistical model: intercept and wavelength range in nanometers (nm)
