Double Saddlepoint Approximation: Properties and Applications
Lobachevskii Journal of Mathematics（2023）
摘要
In this study paper, saddlepoint approximation is considered one of the very accurate methods to derive the exact PMF/PDF and CDF for some complicated distributions. Double saddlepoint approximations provide a quick and accurate approximation to exact conditional tail probability in a variety of situations. However, in this study paper, the conditional saddlepoint approximation has been discussed for some distribution as Poisson and hypergeometric distribution.
