英文摘要:
The Lugannani-Rice formula is a saddlepoint approximation method for estimating the tail probability distribution function, which was originally studied for the sum of independent identically distributed random variables. Because of its tractability, the formula is now widely used in practical financial engineering as an approximation formula for the distribution of a (single) random variable. In this paper, the Lugannani-Rice approximation formula is derived for a general, parametrized sequence of random variables and the order estimates of the approximation are given.

中文摘要:
Lugannani-Rice公式是一种用于估计尾部概率分布函数的鞍点近似方法,最初研究的是独立同分布随机变量之和。由于其易处理性,该公式现在在实际金融工程中被广泛用作(单个)随机变量分布的近似公式。本文导出了一般参数化随机变量序列的Lugannani-Rice近似公式,并给出了近似的阶估计。
