连续观测下遍历粗糙分式Ornstein-Uhlenbeck过程的渐近有效估计

Asymptotically Efficient Estimation of Ergodic Rough Fractional Ornstein-Uhlenbeck Process under Continuous Observations

Kohei Chiba, Tetsuya Takabatake

摘要:

研究了在连续观测下,当Hurst参数$H<1/2$及其平稳分布的均值不为零时,遍历分数阶Ornstein-Uhlenbeck过程漂移参数的渐近有效估计问题.本文给出了漂移参数估计的渐近有效率和方差,并证明了漂移参数极大似然估计的渐近有效性。

英文摘要:

We consider the problem of asymptotically efficient estimation of drift parameters of the ergodic fractional Ornstein-Uhlenbeck process under continuous observations when the Hurst parameter $H<1/2$ and the mean of its stationary distribution is not equal to zero. In this paper, we derive asymptotically efficient rates and variances of estimators of drift parameters and prove an asymptotic efficiency of a maximum likelihood estimator of drift parameters.
