摘要翻译:
在自然科学和社会科学中普遍存在着复杂系统中时间或空间上记录的两个变量相互关联并具有多重分形特征的现象。我们提出了一种新的方法,称为多重分形减分互相关分析(MF-DXA)来研究两个记录之间在一维或更高维的幂律互相关中的多重分形行为。通过一维和二维互相关二项式测度和多重分形随机游动对该方法进行了验证。并举例说明了在两个金融时间序列中的应用。

英文摘要:
It is ubiquitous in natural and social sciences that two variables, recorded temporally or spatially in a complex system, are cross-correlated and possess multifractal features. We propose a new method called multifractal detrended cross-correlation analysis (MF-DXA) to investigate the multifractal behaviors in the power-law cross-correlations between two records in one or higher dimensions. The method is validated with cross-correlated 1D and 2D binomial measures and multifractal random walks. Application to two financial time series is also illustrated.
