  1. The RMSEP values are slightly higher than the uncertainty of the primary analytical methods. The slope and intercept describe the line of best fit for these samples.
  2. RMSEP root-mean-square-error of prediction, R 2 square of the correlation coefficient for the external validation predictions.
