    • sample

      default double sample()
      Description copied from interface: StatisticalDistribution
      Generate a new pseudo random number. If the Antithetic Variates Technique is enabled, the returned value is manipulated to try reducing variance or generated random numbers. Check the provided link for details.
      Specified by:
      sample in interface org.apache.commons.math3.distribution.RealDistribution
      Specified by:
      sample in interface StatisticalDistribution
      Returns:
      the next pseudo random number in the sequence, following the implemented distribution.
