  • Page 50 F-750 Instruction Manual 5/10/2017 The Prediction Error graph displays the reference value vs. the predicted value for both the complete regression and the cross validation. This graph is useful for determining outliers or specimen that do not fit well within the regression.

Thus, a sample scan that fits perfectly within the training set range will yield a model fit number equal to 0, while subsequent deviations will scale according to the wavelength influence and magnitude of deviation.
  • Page 54 F-750 Instruction Manual 5/10/2017 Optimizing the Grape Demo Model: Now we will go back and optimize the grape demo model. To begin, navigate back to the Scores Plot and hover over the Potential Outlier scan in the lower right quadrant. We can see that this is specimen number 239 with the spectra name of r39.
  • Page 55 F-750 Instruction Manual 5/10/2017 change, it can be concluded that specimen 239 is not an outlier and should be included in the training set. Go back to the training set, include #239 and build the model again. Next, look at the Prediction Error graph. Here, you can see that specimen 260 is poorly predicted by the model.
