  1. The t-values are calculated for the differences in accuracy scores between "method X" and "method Y" (x-y) tested on EVAc6 subset 5. The descriptions of DBNN, CM1, CM2 and CM3 can be found in the text. Underlined are where calculated t > tabulated t (significant). The tabulated t = 1.67 for α = 0.05 and degree of freedom = 72.
