英文摘要	In this paper, we investigate the optimal strong convergence rate of numerical approximations for the Cox-Ingersoll-Ross model driven by fractional Brownian motion with Hurst parameter H is an element of (1/2, 1). To deal with the difficulties caused by the unbounded diffusion coefficient, we study an auxiliary equation based on Lamperti transformation. By means of Malliavin calculus, we prove that the backward Euler scheme applied to this auxiliary equation ensures the positivity of the numerical solution, and is of strong order one. Furthermore, a numerical approximation for the original model is obtained and converges with the same order. (C) 2019 Elsevier B.V. All rights reserved.
