Berry-Esseen and Edgeworth approximations for the tail of an infinite sum of weighted gamma random variables

Mark S. Veillette, Murad S. Taqqu

Consider the sum $Z = \sum_{n = 1}^{\infty} λ_{n} (η_{n} - E η_{n})$ , where $η_{n}$ are i.i.d.~gamma random variables with shape parameter $r > 0$ , and the $λ_{n}$ 's are predetermined we…

Using Differential Equations to Obtain Joint Moments of First-Passage Times of Increasing Levy Processes

Mark S. Veillette, Murad S. Taqqu

Let ${D (s), s \geq 0}$ be a Lévy subordinator, that is, a non-decreasing process with stationary and independent increments and suppose that $D (0) = 0$ . We study the first-hitti…

Numerical Computation of First-Passage Times of Increasing Levy Processes

Mark S. Veillette, Murad S. Taqqu

Let ${D (s), s \geq 0}$ be a non-decreasing Lévy process. The first-hitting time process ${E (t) t \geq 0}$ (which is sometimes referred to as an inverse subordinator) defined by…
