  1. *Definitions in Table 6:
  2. TP-True positive;
  3. TN-True negative;
  4. FP-False positive;
  5. FN-False negative.
  6. Nnegative is the number of negative (non-carcinogens) in the dataset;
  7. Npositive is the number of positive compounds (carcinogens) in the dataset;
  8. Ntotal is total number of negative (non-carcinogens) and positive compounds (carcinogens) in the dataset;
