    Second weak order explicit stabilized methods for stiff stochastic differential equations by Abdulle, A, Vilmart, G, Zygalakis, K

    Published 2012
    “…We introduce a new family of explicit integrators for stiff Itˆo stochastic differential equations (SDEs) of weak order two. These numerical methods belong to the class of onestep stabilized methods with extended stability domains and do not suffer from stepsize reduction that standard explicit methods face. …”

    High order weak methods for stochastic differential equations based on modified equations by Abdulle, A, Cohen, D, Vilmart, G, Zygalakis, K

    Published 2011
    “…Inspired by recent advances in the theory of modified differential equations, we propose a new methodology for constructing numerical integrators with high weak order for the time integration of stochastic differential equations. This approach is illustrated with the constructions of new high order weak methods, in particular, implicit integrators well suited for stiff stochastic problems, and integrators that exactly conserve all quadratic first integrals of a stochastic dynamical system. …”

    An improved two-step method in stochastic differential equation's structural parameter estimation by Abd. Rahman, Haliza

    Published 2013
    “…Regression spline characterised by the truncated power series basis with Bayesian approach is considered in the first step of a two-step method for estimating the structural parameters for stochastic differential equation (SDE). Previous methodology revealed the selection of knot and order of spline can be done heuristically based on a scatter plot. …”

    Modification of two-step method in estimating the parameters of stochastic differential equation models by Lazim, N. H. M., Rahman, H. A., Bahar, A.

    Published 2016
    “…Two-step method is introduced as an alternative method to classical methods in estimating the drift and diffusion parameters of the Stochastic Differential Equations (SDEs) models. Previous studies indicated that this method provides high percentage of accuracy of the estimated diffusion parameter of Lotka-Volterra model with simulated data. …”

    Stability analysis of explicit and semi-implicit derivative-free methods for stochastic differential equations by Norhayati, Rosli, Noor Amalina Nisa, Ariffin

    Published 2016
    “…This paper is devoted to investigate the mean-square stability of explicit and semi-implicit derivative-free methods to a class of stochastic differential equations (SDEs). The mean-square stability functions and regions of explicit and semi-implicit numerical approximation schemes are obtained for a linear stochastic differential equation with multiplicative noise. …”

    Comparative study of stochastic Taylor methods and derivative-free methods for stochastic differential equations by Muhammad Fahmi, Ahmad Zuber, Norhayati, Rosli

    Published 2021
    “…However, modelling these systems using deterministic model such as ODEs is inadequate as the system is subjected to the uncontrolled factors of environmental noise. Stochastic differential equations (SDEs) which are originating from the irregular Brownian motion can be applied to model such systems that subjected to the uncontrolled factors of noisy behaviour. …”
