英文摘要:
Long-range correlation and fluctuation in the gold market time series of world\'s two leading gold consuming countries, namely China and India, are studied. For both the market series during the period 1985-2013 we observe a long-range persistence of memory in the sequences of maxima (minima) of returns in successive time windows of fixed length, but the series as a whole are found to be uncorrelated. Multifractal analysis for these series as well as for the sequences of maxima (minima) is carried out in terms of the multifractal detrended fluctuation analysis (MF-DFA) method. We observe a weak multifractal structure for the original series that is mainly originated from the fat-tailed probability distribution function of the values, and the multifractal nature of the original time series is enriched into their sequences of maximal (minimal) returns. A quantitative measure of multifractality is provided by using a set of \"complexity parameters\".

中文摘要:
研究了世界两大黄金消费国中国和印度黄金市场时间序列的长期相关性和波动性。对于1985年至2013年期间的两个市场序列,我们观察到在固定长度的连续时间窗口中,收益的最大值(最小值)序列中存在长期记忆,但发现整个序列不相关。根据多重分形去趋势波动分析(MF-DFA)方法,对这些序列以及最大值(最小值)序列进行多重分形分析。我们观察到原始时间序列的多重分形结构较弱,主要来源于值的厚尾概率分布函数,原始时间序列的多重分形性质丰富到其最大(最小)收益序列中。通过使用一组“复杂性参数”,提供了多重分形的定量度量。
