Abstract In this note we present new perturbation bounds for the stationary distribution of Markov chains with denumerable state space. Bounds are obtained using the Dobrushin’s coefficient δ ( P ) and the ergodic coefficient α ( P ) . Bounds are shown to be relevant when α ( P ) δ ( P ) . In addition we present bounds only involving the coefficient α ( P ) .

可数马尔可夫链平稳分布的敏感性

摘要 在这篇笔记中,我们为具有可数状态空间的马尔可夫链的平稳分布提出了新的扰动边界。使用 Dobrushin 系数 δ ( P ) 和遍历系数 α ( P ) 获得边界。当 α (P) δ (P) 时,边界被证明是相关的。此外,我们提出了仅涉及系数 α ( P ) 的界限。
