Precise large deviations of sums of widely dependent random variables and its applications

Probability 2021-06-14 v1

Abstract

In this paper, we obtain some results on precise large deviations for non-random and random sums of widely dependent random variables with common dominatedly varying tail distribution or consistently varying tail distribution on (,)(-\infty,\infty). Then we apply the results to reinsurance and insurance and give some asymptotic estimates on proportional reinsurance, random-time ruin probability and the finite-time ruin probability.
