Classification with KFDA using hydroxyproline, leucine, and threonine as inputs. Shown are (A) the discriminant scores from fitting, (B) the PDFs of these fitted scores for the ASD and TD study cohorts, and (C) the predicted discriminant scores resulting from leave-one-out cross-validation. The Type I and Type II errors from the fitted PDFs with the shown classification threshold are 4.2% and 5.0%, respectively. Discriminant scores outside the range of [-6, 6] are plotted as darker points at the respective bound, for visualization purposes only. Misclassification errors of the fitted scores are significantly smaller than those of the cross-validated results.
