    public class DBOutlierScore<O>
    extends AbstractDBOutlier<O>
    Compute percentage of neighbors in the given neighborhood with size d.

    Generalization of the DB Outlier Detection by using the fraction as outlier score thus eliminating this parameter and turning the method into a ranking method instead of a labelling one.
