一类非线性随机模型作为金融市场突发行为的背景

The class of nonlinear stochastic models as a background for the bursty behavior in financial markets

Vygintas Gontis, Aleksejus Kononovicius, Stefan Reimann

摘要:

我们调查大的变化,突发,连续的随机信号,当指数的乘法大于1。在此之前,我们已经提出了一个一般的非线性随机模型,它可以转化为贝塞尔过程已知的首达(首达)时间统计。利用这些结果,我们推导出PDF的突发持续时间的模型。通过数值计算确定了解析表达式,并在非线性回归建模的框架下讨论了金融市场收益率的突发行为。

英文摘要:

We investigate large changes, bursts, of the continuous stochastic signals, when the exponent of multiplicativity is higher than one. Earlier we have proposed a general nonlinear stochastic model which can be transformed into Bessel process with known first hitting (first passage) time statistics. Using these results we derive PDF of burst duration for the proposed model. We confirm analytical expressions by numerical evaluation and discuss bursty behavior of return in financial markets in the framework of modeling by nonlinear SDE.
