英文摘要:
The aim here is to study the concept of pairing multifractality between time series possessing non-Gaussian distributions. The increasing number of rare events creates \"criticality\". We show how the pairing between two series is affected by rare events, which we call \"coupled criticality\". A method is proposed for studying the coupled criticality born out of the interaction between two series, using the bivariate multifractal random walk (BiMRW). This method allows studying dependence of the coupled criticality on the criticality of each individual system. This approach is applied to data sets of gold and oil markets, and inflation and unemployment.

中文摘要:
本文的目的是研究具有非高斯分布的时间序列之间的配对多重分形的概念。越来越多的罕见事件造成了“临界”。我们展示了罕见事件如何影响两个系列之间的配对,我们称之为“耦合临界”。提出了一种利用二元多重分形随机游动(BiMRW)研究两个序列相互作用产生的耦合临界性的方法。这种方法允许研究耦合临界性对每个单独系统临界性的依赖性。这种方法适用于黄金和石油市场以及通货膨胀和失业的数据集。
