Spherical Ornstein-Uhlenbeck Processes [PDF]

open access: yesJournal of Statistical Physics, 2011
The paper considers random motion of a point on the surface of a sphere, in the case where the angular velocity is determined by an Ornstein-Uhlenbeck process. The solution is fully characterized by only one dimensionless number, the persistence angle, which is the typical angle of rotation of the object during the correlation time of the angular ...

Data Analysis Using a Coupled System of Ornstein–Uhlenbeck Equations Driven by Lévy Processes

open access: yesAxioms, 2022
In this work, we have analyzed data sets from various fields using a coupled Ornstein–Uhlenbeck (OU) system of equations driven by Lévy processes. The Ornstein–Uhlenbeck model is well known for its ability to capture stochastic behaviors when used as a ...

Pricing Energy Derivatives in Markets Driven by Tempered Stable and CGMY Processes of Ornstein–Uhlenbeck Type

open access: yesRisks, 2022
In this study, we consider the pricing of energy derivatives when the evolution of spot prices follows a tempered stable or a CGMY-driven Ornstein–Uhlenbeck process.

On the Kolmogorov Distance for the Maximum Likelihood Estimator in the Explosive Ornstein-Uhlenbeck Process

open access: yesEuropean Journal of Mathematical Analysis, 2023
The paper estimates the Kolmogorov distance between the distribution of the normalized maximum likelihood estimator of the positive drift parameter in the nonergodic Ornstein-Uhlenbeck process and the standard Cauchy distribution and shows exponential ...

Continuous time volatility modelling: COGARCH versus Ornstein-Uhlenbeck models [PDF]

open access: yes, 2005
We compare the probabilistic properties of the non-Gaussian Ornstein-Uhlenbeck based stochastic volatility model of Barndorff-Nielsen and Shephard (2001) with those of the COGARCH process.

European call option issued on a bond governed by a geometric or a fractional geometric Ornstein-Uhlenbeck process

open access: yesModern Stochastics: Theory and Applications, 2014
European call option issued on a bond governed by a modified geometric Ornstein-Uhlenbeck process, is investigated. Objective price of such option as a function of the mean and the variance of a geometric Ornstein-Uhlenbeck process is studied.

Symmetry of the isotropic Ornstein-Uhlenbeck process in a force field [PDF]

open access: yesOpen Communications in Nonlinear Mathematical Physics, 2021
We classify simple symmetries for an Ornstein-Uhlenbeck process, describing a particle in an external force field $f(x)$. It turns out that for sufficiently regular (in a sense to be defined) forces there are nontrivial symmetries only if $f(x)$ is at ...

Modeling Wind Speed Based on Fractional Ornstein-Uhlenbeck Process

open access: yesEnergies, 2021
The primary task of the design and feasibility study for the use of wind power plants is to predict changes in wind speeds at the site of power system installation.

Ornstein–Uhlenbeck process with fluctuating damping [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2018
This paper studies Langevin equation with random damping due to multiplicative noise and its solution. Two types of multiplicative noise, namely the dichotomous noise and fractional Gaussian noise are considered. Their solutions are obtained explicitly, with the expressions of the mean and covariance determined explicitly.
