The Poisson cumulative distribution function (CDF) \begin{equation} F(α,n) = \sum_{k=0}^n \dfrac{α^k}{k!} \; e^{-α} \label{eqn:pcdf} \end{equation} is the probability of at most $n$ events occurring when the average number of events is α, i.e., $\Pr(
Theorem: In the limit n→∞ and p→ 0 so that the mean value np→ μ stays finite, the binomial distribution becomes a Poisson distribution. To prove this theorem, we need to find the large-n limit of the binomial distribution formula, Eq. (23.42). To do so, we apply Stirling's fo...

Suppose that \(X_{1},X_{2},\ldots , X_{n}\) be a random sample of size n follows the ILUP distribution with CDF and PDF given in Eqs. (9 and 10), respectively with the parameters \(\lambda , \beta , \theta\) and let \(X_{1:n},X_{2:n},\ldots , X_{n:n}\) ...
The geometric Poisson distribution (also called PlyaAeppli) is a particular case of the compound Poisson distribution. We propose to express the general term of this distribution through a recurrence formula leading to a linear algorithm for the computation of its cumulative distribution function. Pract...
