摘要

从超统计的扩展角度提出了时间序列分析的应用,其中引入了具有幂律 Em-1 状态密度的波尔兹曼分布。这种超统计情景是由伽马分布的叠加产生的,这在一些论文中已经有所暗示。我们对 SYM-H 地磁指数的大小提取了两个时间序列,涵盖了太阳周期 22 和 24 之间的时期,并提取了太阳活动最小和最大的数据。从拟议的超统计角度对相应的时间序列进行了分析,结果表明它们之间存在一致性,表明它们都是类似超统计过程的结果。

Testing the scope of superstatistical time series analysis: Application to the SYM-H geomagnetic index
An application of time series analysis is proposed from a extended perspective of superstatistics, in which a Boltzmann-like distribution with a power law Em1 density of states has been introduced. This superstatistical scenario is one generated by a superposition of gamma distributions, which has already been hinted in some papers. Two time series for the magnitude of SYM-H geomagnetic index have been taken, covering periods between solar cycles 22 and 24, where data of minimum and maximum solar activity have been extracted. Analyzes were performed from the proposed superstatistical perspective to the corresponding time series, showing concordance that could suggest that each of them is a consequence of a superstatistical-like process.

期刊介绍: Physica A: Statistical Mechanics and its Applications Recognized by the European Physical Society Physica A publishes research in the field of statistical mechanics and its applications. Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents. Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
