关于吸收马氏过程的拟遍历分布

On the quasi-ergodic distribution of absorbing Markov processes

Guoman He, Hanjun Zhang, Yixia Zhu

摘要:

本文给出了吸收马氏过程存在拟遍历分布的一个充分条件。利用正交多项式方法,证明了前面的主要结果对于以0为吸收边界,以$\infty$为入口边界的非负整数上的纯灭过程是有效的.我们还证明了出生-纯灭过程的拟遍历分布在单调似然比序意义下随机大于唯一拟平稳分布。

英文摘要:

In this paper, we give a sufficient condition for the existence of a quasi-ergodic distribution for absorbing Markov processes. Using an orthogonal-polynomial approach, we prove that the previous main result is valid for the birth-death process on the nonnegative integers with 0 an absorbing boundary and $\infty$ an entrance boundary. We also show that the quasi-ergodic distribution is stochastically larger than the unique quasi-stationary distribution in the sense of monotone likelihood-ratio ordering for the birth-death process.
