Lower bound of precise large deviation for partial sums of END random variables with long tails in a multi-risk model |

| Abstract: | In view of the actual condition of the insurance company, a multi-risk model is proposed, the precise large deviation for partial sums of random variables with long tailed distributions is investigated, where the sequence of random variables is a sequence of extended negatively dependent and identically distributed random variables, and the asymptotic lower bound of large deviation for partial sums of random variables by using the proof method basing on the results of precise large deviations for long tailed distributions is obtained. |
