BM, MCC and MK for classifiers with known randomness. We simulated classifiers with known amounts of randomness. To that purpose, we generated random lists of reference classes with a given prevalence. A fraction of those classes were copied (called lookup fraction) and used as predicted labels, the remaining ones were generated randomly, matching a given bias. Matching the reference classes with the prediction labels we determined bookmaker informedness, Matthews correlation coefficient and markedness (left, center and right column respectively). The rows differ by the amount of randomness/lookup fraction
