摘    要:弱化Scott与Tweedie在计算马氏链收敛速度界时的条件,即变一步转移概率为m(m≥1)步转移概率,并运用不同于Scott与Tweedie的方法,计算出马氏链几何收敛速度r~n的界,从而推广了已有的结论.

关 键 词:马尔可夫链  m-骨架  漂移不等式  f-遍历  收敛速度

Abstract:Scott and Tweedie find condition under which there are bounds on the conve'rgence rates of Markov chains.This paper is an attempt to weaken that condition,that is,I manage to change one-step transition probability into m-step transition probability.At the same time,by using the different means from Scott and Tweedie,I compute the bounds for geometric convergence rates r~n of Markov chains,and therefore generalize the existent results.
Keywords:Markov chains  m-skeleton  drift inequality  f-ergodic  convergence rate
