    • testNextPoisson

      public void testNextPoisson()
      确保随机Poisson(4)的经验分布具有P(X <= 5)接近实际累积泊松概率，并且当均值为非正时，nextPoisson会失败。

    • testNextPoissonConsistency

      public void testNextPoissonConsistency()

    • checkNextPoissonConsistency

      public void checkNextPoissonConsistency(double mean)
      验证nextPoisson(mean)生成的值的经验分布与PoissonDistributionImpl一致，方法是生成1000个值，计算观察到的值的分组频率分布，并将此分布与使用PoissonDistributionImpl计算的相应预期分布进行比较。使用卡方拟合度检验来评估零假设，即分布相同。如果可以以置信度1 - alpha拒绝零假设，则检查失败。
