LAN Property for the Drift and Hurst Paramters in The Mixed Fractional O-U Process with Continuous Observations

Probability 2025-10-21 v1

Abstract

This paper deals with the Local Asymptotical normality for the joint drift parameter and Hurst parameter H>3/4H>3/4 in the mixed fractional Ornstein-Uhlenbeck process. Different from the only estimation of the drift parameter when HH is known, we will use the fact that the mixed fractional Brownian motion is a semimartingale with its own filtering when H>3/4H>3/4.
