;; Each list in the following list consists of two elements,
;; the second element being the number of splits in the dataset
;; that have a left-hand set cardinality equal to the first element.
;; The cardinality of the union set (i.e. the universe of discourse)
;; is 4909.  We must be able to exploit this non-uniformity.
