双指数Ornstein-Ulenbeck过程的遍历估计

Ergodic Estimators of double exponential Ornstein-Ulenbeck process

Yaozhong Hu, Neha Sharma

摘要:

本文的目标是构造双指数Ornstein-Uhlenbeck过程中参数的各态历经估计,该过程在时间步长为h的离散时刻观察。对于任意固定的时间步长h,得到了估计的存在唯一性、强相合性和渐近正态性.提出了双指数Ornstein-Uhlenbeck过程的一种模拟方法,并进行了数值模拟,验证了所提估计器的有效性。

英文摘要:

The goal of this paper is to construct ergodic estimators for the parameters in the double exponential Ornstein-Uhlenbeck process, observed at discrete time instants with time step size h. The existence and uniqueness, the strong consistency, and the asymptotic normality of the estimators are obtained for arbitrarily fixed time step size h. A simulation method of the double exponential Ornstein-Uhlenbeck process is proposed and some numerical simulations are performed to demonstrate the effectiveness of the proposed estimators.
