摘要
In this paper, we study the Berry-Esseen bound of the distribution of the maximum likelihood estimation in some inhomogeneous diffusions. We prove that it converges to the normal distribution with an error rate 0((- log integral(T)(t) sigma(2)(s)ds)(-1/2)). Moreover, the obtained Berry-Esseen bound can be applied to study the precise asymptotics in the law of iterated logarithm for the maximum likelihood estimation. (C) 2011 Elsevier B.V.
