英文摘要:
In this short report, we investigate the ability of the DCCA coefficient to measure correlation level between non-stationary series. Based on a wide Monte Carlo simulation study, we show that the DCCA coefficient can estimate the correlation coefficient accurately regardless the strength of non-stationarity (measured by the fractional differencing parameter $d$). For a comparison, we also report the results for the standard Pearson\'s correlation coefficient. The DCCA coefficient dominates the Pearson\'s coefficient for non-stationary series.

中文摘要:
在这篇简短的报告中,我们研究了DCCA系数测量非平稳序列之间相关性水平的能力。基于广泛的Monte Carlo模拟研究,我们表明DCCA系数可以准确估计相关系数,而不考虑非平稳性的强度(由分数差分参数$d$测量)。为了进行比较,我们还报告了标准皮尔逊相关系数的结果。对于非平稳序列,DCCA系数主导皮尔逊系数。
