The first graph shows the distribution of the projected points in these two components. The second graph shows the contribution of each of the DEQ questions to the first two principal components. b Shows classification error obtained in the model calibration process, using different search algorithms. The Tabu search algorithm was selected due to its lower average classification error and lower variance in the cross-validation sample
