稳定过程的多元从属性

Multivariate subordination of stable processes

V. Panov, E. Samarin

摘要:

本文主要研究基于多变量稳定过程的时变随机模型。与经典的时变布朗运动相比,所考虑的模型有几个优点-例如,事实证明,如果交易量用于随机时变,它们更适合于描述股票价格。在本文中,我们提供了一个详细的讨论模型,这是基于两个流行的概念-多元从属和L{é}vy copula。

英文摘要:

This article is devoted to some time-changed stochastic models based on multivariate stable processes. The considered models have several advantages in comparison with classical time-changed Brownian motions - for instance, it turns out that they are more appropriate for describing stock prices if the amount of transactions is used for a stochastic time change. In this paper, we provide a detailed discussion of the model, which is based on two popular concepts - multivariate subordination and L{é}vy copulas.
