Approximation of the difference of two Poisson-like counts with Skellam
H. L. Gan, Eric D. Kolaczyk
Poisson-like behavior for event count data is ubiquitous in nature. At the same time, differencing of such counts arises in the course of data processing in a variety of areas of a…

Improving approximation error bounds via truncation
H. L. Gan
One aspect of Poisson approximation is that the support of the random variable of interest is often finite while the support of the Poisson distribution is not. In this paper we wi…
