摘要：
We study a problem of parametric estimation for continuously observed stochastic processes involving fractional Brownian motion with Hurst index H is an element of (1 /2, 1). Under some assumptions on the drift and volatility coefficients, we obtain the asymptotic normality and moment convergence of maximum likelihood type estimator of the drift parameter under the small noise asymptotics such that the driving noise vanishes.
