  • Constructor Details

    • DistDiscrete

      public DistDiscrete(StreamInterface stream)
      constructs a new discrete distribution.
      Parameters:
      stream - the random number stream

  • Method Details

    • draw

      public abstract long draw()
      draws the next long from the stream.
      Returns:
      long

    • probability

      public abstract double probability(long observation)
      returns the probability of the observation in this particular distribution.
      Parameters:
      observation - the discrete observation.
      Returns:
      double the probability.
