Pathwise skew-symmetric discretisation for SDEs with superlinear drift
Yuga Iguchi, Samuel Livingstone, Giorgos Vasdekis +1
The skew-symmetric discretisation has recently been proposed as a new robust simulation method for weakly approximating stochastic differential equations (SDEs) with non-globally L…
Parameter Estimation for Weakly Interacting Hypoelliptic Diffusions
Yuga Iguchi, Alexandros Beskos, Grigorios A. Pavliotis
We study parameter estimation for interacting particle systems (IPSs) consisting of weakly interacting multivariate hypoelliptic SDEs. We propose a locally Gaussian approximati…
A Closed-Form Transition Density Expansion for Elliptic and Hypo-Elliptic SDEs
Yuga Iguchi, Alexandros Beskos
We introduce a closed-form expansion for the transition density of elliptic and hypo-elliptic multivariate Stochastic Differential Equations (SDEs), over a period , in…
Antithetic Multilevel Methods for Elliptic and Hypo-Elliptic Diffusions with Applications
Yuga Iguchi, Ajay Jasra, Mohamed Maama +1
We present a new antithetic multilevel Monte Carlo (MLMC) method for the estimation of expectations with respect to laws of diffusion processes that can be elliptic or hypo-ellipti…
