      • score

        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.

        public abstract String toString()
        Subclasses must override this method to return the name of the distribution.
        Overrides:
