Abstract:
Consider a sequence of independent and identically distributed non-degenerate real-valued random variables with a finite second moment. We obtain precise asymptotic estimates for the probabilities of moderate deviations of the partial sums. Those known results under assumption of high moments in the literature depend on the variance of the underlying distribution only. The moderate deviation results established in this paper depend on both the variance and the asymptotic tail behavior of the underlying distribution.
