分数阶Gompertz扩散过程的Hurst指数和扩散系数估计的比较

On comparison of the estimators of the Hurst index and the diffusion coefficient of the fractional Gompertz diffusion process

Kestutis Kubilius, Dmitrij Melichov

摘要:

研究了分数阶Gompertz扩散过程的Hurst指数和扩散系数的一些估计,证明了它们是强相合的,且大多数是渐近正态的.此外,我们还借助计算机模拟比较了这些估计量的渐进行为。

英文摘要:

We study some estimators of the Hurst index and the diffusion coefficient of the fractional Gompertz diffusion process and prove that they are strongly consistent and most of them are asymptotically normal. Moreover, we compare the asymptotic behavior of these estimators with the aid of computer simulations.
