Minimum Entropy Density Method for the Time Series Analysis

Jeong Won Lee, Joongwoo Brian Park, Hang-Hyun Jo, Jae-Suk Yang, Hie-Tae Moon

摘要:

熵密度是研究物理系统中复杂非线性过程的一个直观而有力的概念。我们发展了最小熵密度方法(MEDM)来检测一个给定的时间序列的结构规模,它被定义为规模的不确定性是最小的,因此模式被揭示最多。本文将MEDM方法应用于1983年2月至2006年4月标准普尔500指数的金融时间序列。在此基础上,分析了信息传递时间和有效市场假说对结构规模的影响。

英文摘要:

The entropy density is an intuitive and powerful concept to study the complicated nonlinear processes derived from physical systems. We develop the minimum entropy density method (MEDM) to detect the structure scale of a given time series, which is defined as the scale in which the uncertainty is minimized, hence the pattern is revealed most. The MEDM is applied to the financial time series of Standard and Poor's 500 index from February 1983 to April 2006. Then the temporal behavior of structure scale is obtained and analyzed in relation to the information delivery time and efficient market hypothesis.
