摘要
应用赫斯特提出的重标极差分析法(RescaledRangeAnalysis)即R/S分析法,研究金融时间序列,通过对上海股票市场综合指数日收益数据的实证分析,认为上海股票市场具有分形结构,收益率时间序列是有偏的随机游走.
In the paper, the Rescaled Range Analysis (R/S) is used to study financial time series. Study of the data of day-returns in Shanghai Stock Market shows Shanghai Stock Market is a fractal market and the series of day-returns is a biased random walk process.
