随机微分方程中分数布朗运动Hurst指数估计收敛速率

The rate of convergence of estimate for Hurst index of fractional Brownian motion involved into stochastic differential equation

K. Kubilius, Y. Mishura

摘要:

考虑关于分数阶布朗运动的含路径积分的随机微分方程。Hurst参数的估计是根据解的观测值的一阶和二阶二次变异构造的。这些估计值的收敛速度收敛速率的参数的真实值的建立。

英文摘要:

We consider stochastic differential equation involving pathwise integral with respect to fractional Brownian motion. The estimates for the Hurst parameter are constructed according to first- and second-order quadratic variations of observed values of the solution. The rate of convergence of these estimates to the true value of a parameter is established.
