Let {Xn,n ³1} be a sequence of m-dependent random variables with survival function F(x) = P{X1 > x}. The empirical survival function Fn(x) based on X1,…, Xn is proposed as an estimator for F(x) . In this paper, we obtain some asymptotic results of the survival function estimator, which improve and extend the works of Zarei in [9].
