        public abstract double score​(BasicStats stats,
                                     double tfn,
                                     double lambda)
        Computes the score.
      • explain

        public Explanation explain​(BasicStats stats,
                                   double tfn,
                                   double lambda)
        Explains the score. Returns the name of the model only, since both tfn and lambda are explained elsewhere.
