摘要:

This paper deals with the problems of consistency and strong consistency of the maximum likelihood estimators of the mean and variance of the drift fractional Brownian motions observed at discrete time instants. Both the central limit theorem and the Berry-Ess´een bounds for these estimators are obtained by using the Stein’s method via Malliavin calculus.

关键词: maximum likelihood estimator, fractional Brownian motions, strong consis-tency, central limit theorem, Berry-Ess´een bounds Stein’s method, Malli-avin calculus
