去趋势互相关分析:分析两个非平稳时间序列的新方法
Detrended Cross-Correlation Analysis: A New Method for Analyzing Two Non-stationary Time Series
摘要:
在这里,我们提出了一种方法,基于去趋势协方差,我们称之为去趋势互相关分析(DXA),调查非平稳性存在的情况下,不同的错误记录的时间序列之间的幂律互相关。我们通过从物理学、生理学和金融学中选择的例子来说明这种方法。
英文摘要:
Here we propose a method, based on detrended covariance which we call detrended cross-correlation analysis (DXA), to investigate power-law cross-correlations between different simultaneously-recorded time series in the presence of non-stationarity. We illustrate the method by selected examples from physics, physiology, and finance.
