The figure shows simulating and CC values according to different proportions of TP, TN, FP, and FN. On the -axis are reported the different proportions of total true responses from 100 to 0% and, therefore, the symmetrical proportion of total false responses. On the -axis are reported the proportions of TP and TN for each level of total true responses. On the -axis are reported the ratio values. In this figure, we have balanced the total false responses as 50% FP and 50% FN. This explains that and CC have very close negative values.
