Graph of changes in ACC as a function of Δ m for the three compared methods: method 1- thresholding, method 2- decision trees and method 3- discriminant analysis. The worst results of classification of patients with Hashimoto’s disease (ACC=77%) were obtained for the method of thresholding of echogenicity average levels (red). Comparable results for Δm=0 were obtained for decision trees and discriminant analysis. Here discriminant analysis is characterized by smaller changes in accuracy for different positions of the ROI.
