Invariance properties of the negative binomial Levy process and stochastic self-similarity.

Kozubowski, Tomasz and Podgorski, Krzysztof LU (2007) In International Mathematical Forum 2(30). p.1457-1468
Abstract
We study the concept of self-similarity with respect to stochastic

time change. The negative binomial process (NBP) is an example of a

family of random time transformations with respect to which stochastic

self-similarity holds for certain stochastic processes. These processes

include gamma process, geometric stable processes, Laplace motion, and

fractional Laplace motion. We derive invariance properties of the NBP

with respect to random time deformations in connection with stochastic

self-similarity. In particular, we obtain more general classes of processes

that exhibit stochastic self-similarity properties. As an application, our

results lead to... (More)

simulation algorithms for both processes. (Less)
