Dispersion of the observed and predicted values for the Leaf Nitrogen Content - LNC in sugarcane from the general (450–2000 nm) and effective (400–750 nm) spectral data, using the validation technique LOOCV, with a validation with seven collections and a validation with only one which did not participate in the prediction (Fig. 7a.) and holdout, where 70% of the data were used for prediction and 30% for validation (Fig. 7b.).
