Is a Brownian Motion Skew? [PDF]

open access: yesScandinavian Journal of Statistics, 2013
ABSTRACTWe study the asymptotic behaviour of the maximum likelihood estimator corresponding to the observation of a trajectory of a skew Brownian motion, through a uniform time discretization. We characterize the speed of convergence and the limiting distribution when the step size goes to zero, which in this case are non‐classical, under the null ...

Skew brownian motion and complexity of the alps algorithm [PDF]

open access: yesJournal of Applied Probability, 2022
AbstractSimulated tempering is a popular method of allowing Markov chain Monte Carlo algorithms to move between modes of a multimodal target density $\pi$ . Tawn, Moores and Roberts (2021) introduces the Annealed Leap-Point Sampler (ALPS) to allow for rapid movement between modes.

Two consistent estimators for the skew Brownian motion [PDF]

open access: yesESAIM: Probability and Statistics, 2019
The skew Brownian motion (SBm) is of primary importance in modeling diffusion in media with interfaces which arise in many domains ranging from population ecology to geophysics and finance. We show that the maximum likelihood procedure estimates consistently the parameter of an SBm observed at discrete times. The difficulties arise because the observed

Coalescence of Skew Brownian Motions [PDF]

open access: yes, 2001
We prove that two skew Brownian motions with the same skewness parameter (different from 0) and driven by the same Brownian motion coalesce a.s.

DENSITY OF SKEW BROWNIAN MOTION AND ITS FUNCTIONALS WITH APPLICATION IN FINANCE [PDF]

open access: yesMathematical Finance, 2016
AbstractWe derive the joint density of a Skew Brownian motion, its last visit to the origin, its local and occupation times. The result enables us to obtain explicit analytical formulas for pricing European options under both a two‐valued local volatility model and a displaced diffusion model with constrained volatility.

Maximum likelihood estimator for skew Brownian motion: The convergence rate

open access: yesScandinavian Journal of Statistics, 2023
AbstractWe give a thorough description of the asymptotic property of the maximum likelihood estimator (MLE) of the skewness parameter of a Skew Brownian Motion (SBM). Thanks to recent results on the Central Limit Theorem of the rate of convergence of estimators for the SBM, we prove a conjecture left open that the MLE has asymptotically a mixed normal ...

Rates of convergence to the local time of oscillating and skew Brownian motion

open access: yesBernoulli
In this paper, a class of statistics based on high frequency observations of oscillating and skew Brownian motion is considered. Their convergence rate towards the local time of the underlying process is obtained in form of a functional limit theorem. Oscillating and skew Brownian motion are solutions to stochastic differential equations with singular ...
