    • constructFromLists

      public static <T1,T2> PairDistribution<T1,T2> constructFromLists(List<T1> first, List<T2> second)
      Generates the counts for two vectors. Returns a PairDistribution containing the joint count, and the two marginal counts.
      Type Parameters:
      T1 - Type of the first array.
      T2 - Type of the second array.
      Parameters:
      first - An array of values.
      second - Another array of values.
      Returns:
      The joint counts and the two marginal counts.
