ABSTRACT.
Multiple stochastic integrals of higher multiplicity cannot always be expressed in terms of simpler stochastic integrals, especially when the Wiener process is multi-dimensional. In this paper, we show by the Matlab implementation an order one error bounds for Davie’s scheme (Davie, 2015) in section (8) for the Lp space assuming the invertibility of the diffusion matrix. We give a numerical example to show the convergence behavior for 2-dimensional SDE using an explicit
version for the coefficients.
