稳态下事件计数统计量与等待时间统计量之间的关系

Relationship between event counting statistics and waiting time statistics in the steady state

Seong Jun Park, M. Y. Choi

AI总结:

针对非更新过程中等待时间间隔统计与事件计数统计关系不明的问题,本文给出二者的显式关系式,其可涵盖更新过程,并经多个非更新案例验证准确。

摘要:

随机过程偏离 Poisson 过程涉及两个主要量:相邻事件之间时间间隔的平方变异系数,以及反应事件数的 Fano 因子。众所周知,这两个量在更新过程中相等,但对于非更新过程,它们之间的关系仍未得到探究。本文建立了这两个统计量之间适用于非更新过程的显式关系。该新关系在更新过程情形下可退化为前述结果,并在多个非更新过程案例中被证实是准确的。

英文摘要:

There are two main quantities involved in the deviation of a stochastic process from a Poisson process: the squared coefficient of variation of the time intervals between adjacent events and the Fano factor of the number of reaction events. As well known, these two quantities are equal for renewal processes, while their relationship remains unexplored for non-renewal processes. In this paper, we establish an explicit relation between the two statistics that is applicable to non-renewal processes. The new relation, which reduces to the previously mentioned result for renewal processes, is confirmed to be accurate in several cases of non-renewal processes.
