Abstract:
Let {Xn ,n≥1} be a martingale difference sequence and Sn=∑^ni=1xi,n≥1. Suppose {Xn ,n≥1} is bounded in L^p. This paper studies the large deviations for the partial sums of mixing sequences and M-Z sequences, and obtains the similar results optimal upper bounds forμ(|Sn|〉 n) as those for martingale difference sequence.[著者文摘]
Key words:
Large deviations ;p -mixing sequence; ψ-mixing sequence, M-Z sequence
