First passages in bounded domains: When is the mean first passage time meaningful?

TG Mattos, C Mejía-Monasterio, R Metzler… - Physical Review E …, 2012 - APS
We study the first passage statistics to adsorbing boundaries of a Brownian motion in
bounded two-dimensional domains of different shapes and configurations of the adsorbing …

Fat-tailed models for risk estimation

SV Stoyanov, ST Rachev, B Racheva-Iotova… - 2011 - econstor.eu
In the post-crisis era, financial institutions seem to be more aware of the risks posed by
extreme events. Even though there are attempts to adapt methodologies drawing from the …

Non-Gaussian quasi-likelihood estimation of SDE driven by locally stable Lévy process

H Masuda - Stochastic Processes and their Applications, 2019 - Elsevier
We address estimation of parametric coefficients of a pure-jump Lévy driven univariate
stochastic differential equation (SDE) model, which is observed at high frequency over a …

[HTML][HTML] Modeling and simulation of financial returns under non-Gaussian distributions

F De Domenico, G Livan, G Montagna… - Physica A: Statistical …, 2023 - Elsevier
It is well known that the probability distribution of high-frequency financial returns is
characterized by a leptokurtic, heavy-tailed shape. This behavior undermines the typical …

[图书][B] Handbook of heavy-tailed distributions in asset management and risk management

ML Bianchi, SV Stoyanov, GL Tassinari, FJ Fabozzi… - 2019 - World Scientific
