广义逆高斯分布与第一个能级交叉时刻

Generalized inverse Gaussian distributions and the time of first level crossing

Vsevolod K. Malinovskii

摘要:

本文提出了一种新的高阶$u$与随机过程$\homV{s}-cs$首次交叉时刻分布的近似方法,其中$\homV{s}$,$s>0$是复合更新过程,$c>0$是随机过程.它显着优于现有的近似,特别是在附近的区域的临界点$c=\cS$,分离过程的积极和消极的漂移。这种近似与广义逆高斯分布密切相关。

英文摘要:

We propose a new approximation for the distribution of the time of the first crossing of a high level $u$ by random process $\homV{s}-cs$, where $\homV{s}$, $s>0$, is compound renewal process and $c>0$. It significantly outperforms the existing approximations, particularly in the region around the critical point $c=\cS$ which separates processes with positive and negative drifts. This approximation is tightly related to generalized inverse Gaussian distributions.
