TABLE 2. Contingency table which obeys the marginal distribution of species, i.e., the species A and B are uncorrelated. As expected, Fisher's Exact test and its mid-P variant, described later, imply no or weak correlation (the values of indices being 0.74 and 0.53, respectively). Jaccard, Dice, Kulczynski, and Ochiai, on the other hand, all output a high value of similarity (0.82, 0.90, 0.90, and 0.90, respectively).
