Table 2. Pairwise comparison result of the Nemenyi test on PHCA against SVM, RF, KNN, LDA, and CART for the Balanced dataset.

If the value is greater than the threshold value $\alpha =0.05$, then there is a significant difference in terms of overall performance between the compared classifiers. Otherwise, there is no significant difference in overall performance. The bold values indicate the significant performance differences.
