In this paper, we study the asymptotic behavior of maximum likelihood estimators for Ornstein–Uhlenbeck process with large linear drift dXt=1𝜀(𝜃Xt𝜀12ν)dt+dBt, 0tT, where 𝜃,ν, and {Bt}t0 is a given standard Brownian motion. The law of iterated logarithm, consistency and asymptotic distributions of the estimators are discussed based on the continuous observation {Xt}t[0,T] as 𝜀0.

在本文中,我们研究了具有大线性漂移的 Ornstein-Uhlenbeck 过程的最大似然估计量的渐近行为dXt=-1𝜀𝜃Xt-𝜀12νdt+dt,0t时间, 在哪里𝜃,νε, 和{t}t0是给定的标准布朗运动。基于连续观测,讨论了估计量的迭代对数规律、一致性规律和渐近分布规律{Xt}tε[0,时间]作为𝜀0
