  • Constructor Details

    • DistEmpiricalDiscreteLong

      public DistEmpiricalDiscreteLong(StreamInterface stream, DiscreteEmpiricalDistribution empiricalDistribution)
      constructs a new DistEmpirical distribution.
      Parameters:
      stream - the stream to use
      empiricalDistribution - the cumulative distribution to use
      Throws:
      IllegalArgumentException - when the empirical distribution has non-integer values

  • Method Details

    • draw

      public long draw()
      Description copied from class: DistDiscrete
      draws the next long from the stream.
      Specified by:
      draw in class DistDiscrete
      Returns:
      long

    • probability

      public double probability(long observation)
      Description copied from class: DistDiscrete
      returns the probability of the observation in this particular distribution.
      Specified by:
      probability in class DistDiscrete
      Parameters:
      observation - the discrete observation.
      Returns:
      double the probability.
