对于一类满足指数或多项式混合的非均匀遍历马尔可夫链(Xn),在受正密度IID噪声影响的观测值(Yn)下,证明了在平均全变分拓扑中错误的初始数据以一定的指数或多项式速率被遗忘。
For a class ofnon-uniformlyergodic Markov chains (Xn) satisfying exponential or polynomial beta-mixing, under observations (Yn) subject to an IID noise with a positive density, it is shown that wrong initial data is forgotten in the mean total variation topology, with a certain exponential or polynomial rate.
