poisson approximation造句

• Compound poisson approximation of individual risk models
  个体风险模型的复合poisson逼近
• Individual risk models approximation by compound poisson approximation is discussed . three principles are presented , and the optimal choice of poisson parameters under the three principles is discussed . it is proved that the individual risk model is also a compound binomial model ; and formulas on the calculation of the optimal parameters are given . for two distributions , exponential and pareto , calculating results are given
  具体讨论个体风险模型的复合poisson逼近。引入了3个准则，在这3个准则下，分别讨论poisson参数的选取。证明了个体风险模型为一复合二项分布模型在3种准则下，讨论了参数的计算，并给出参数的计算公式对指数分布和pareto分布，给出计算结果。
