摘要
Let us consider a stochastic differential equation driven by a fractional Brownian motion with Hurst parameter 1/4<H<1/2. We are interested in estimating the drift parameter from the completely observed data. We propose an M-estimator for the drift parameter. Under some assumptions on the drift coefficient, our estimator has consistency, asymptotic normality and moment convergence property.
