摘要
引用极限对数似然比的概念作为任意随机序列联合分布与其边缘分布“不相似性”的度量,构造几乎处处收敛的上鞅,讨论了任意离散随机序列的强偏差定理.
In this paper, the notion of limit logarithmic likelihood ratio of stochastic sequences, as a measure of “dissimilarity” between their joint distributions and the product of their marginals, is introduced. Construct convergence super-martingale, a strong deviation theorem for arbitrary discrete stochastic sequence is obtained.
