In this paper, we study the least-squares estimation problem for the Vasicek model driven by the complex fractional Brownian motion where is a two-dimensional fractional Brownian motion with Hurst parameter We obtain the strong consistency and asymptotic normality of and using the Garsia–Rodemich–Rumsey inequality and complex fourth moment theorems.

由复分数布朗运动驱动的 Vasicek 模型的最小二乘估计
在本文中,我们研究了 Vasicek 模型的最小二乘估计问题由复分数布朗运动驱动在哪里是具有赫斯特参数的二维分数布朗运动我们得到强一致性和渐近正态性和使用 Garsia-Rodemich-Rumsey 不等式和复四阶矩定理。
