关于离散逼近的Stein算子

On Stein operators for discrete approximations

N. S. Upadhye, V. Cekanavicius, P. Vellaisamy

摘要:

本文用一种基于概率母函数的新方法,求出了与泊松、二项和负二项分布密切相关的各种随机变量的多重Stein算子。此外,Stein算子的某些复合分布,其中的随机和满足Panjer的递归关系,推导。一个众所周知的摄动方法的斯坦的方法是用来获得全变差的界限,上述分布。举例来说,通过对独立和相依指示随机变量之和的二项式卷积与泊松近似来说明这种近似的重要性。

英文摘要:

In this paper, a new method based on probability generating functions is used to obtain multiple Stein operators for various random variables closely related to Poisson, binomial and negative binomial distributions. Also, Stein operators for certain compound distributions, where the random summand satisfies Panjer's recurrence relation, are derived. A well-known perturbation approach for Stein's method is used to obtain total variation bounds for the distributions mentioned above. The importance of such approximations is illustrated, for example, by the binomial convoluted with Poisson approximation to sums of independent and dependent indicator random variables.
