On the fractional Poisson process and the discretized stable subordinator

TL;DR: In this paper, the renewal counting number process N = N(t) is considered as a forward march over the non-negative integers with independent identically distributed waiting times, and the Laplace transform with respect to both variables x and t is applied.

Integer‐valued Trawl Processes: A Class of Stationary Infinitely Divisible Processes

TL;DR: In this article, the authors introduce a new continuous-time framework for modelling serially correlated count and integer-valued data and apply it to high-frequency financial data, where the key component in their new model is the class of integervalued trawl processes, which are serially correlation, stationary, infinitely divisible processes.

Realized Laplace transforms for estimation of jump diffusive volatility models

TL;DR: In this paper, the authors developed an efficient and analytically tractable method for estimation of parametric volatility models that is robust to price-level jumps, which involves first integrating intra-day data into the Realized Laplace Transform of volatility, which is a model free estimate of the daily integrated empirical Laplace transform of the unobservable volatility.

MMSE Estimation of Sparse Lévy Processes

TL;DR: This work investigates a stochastic signal-processing framework for signals with sparse derivatives, where the samples of a Lévy process are corrupted by noise, and proposes a novel non-iterative implementation of the MMSE estimator based on the belief-propagation (BP) algorithm performed in the Fourier domain.
