important characteristic of the Coefficient of Jaccard is that it discounts the influence of mutual absence in any correlation; this is an advantage in that it avoids unreasonably high correlations between two rare classes, whose only similarity lies in the fact that they are absevt from most of the site. On the other
hand, it minimizes the coefficient between two classes where one of them occurs frequently, and the other only rarely (viz. the surprisingly low coefficient of 0.373 between classes I1 and 111). The Simple Matching Coefficient avoids this pitfall, but errs in overestimating the similarity between small classes (viz. the
