The rescaled variance statistic and the determination of the Hurst exponent

A major issue in statistical physics literature is the study of the long range dependence phenomenon usually presented in natural, social and financial processes. In particular, a big part of this literature relies on the determination of a parameter known as the Hurst exponent. Although many methods have been proposed to deal with this task, none of them are suitable for any time series and so...

Investigation of rescaled range analysis, the Hurst exponent, and long-time correlations in plasma turbulence

A detailed investigation of rescaled range (R/S) analysis to search for long-time correlations ~via the Hurst exponent, H) in plasma turbulence is presented. In order to elucidate important issues related to R/S analysis, structure functions ~SFs!, one of several techniques available for calculating H, are also applied, and comparisons between the two methods are made. Time records of both simu...

Bootstrapping the Small Sample Critical Values of the Rescaled Range Statistic *

Finite sample critical values of the rescaled range or R/S statistic may be obtained by bootstrapping. The empirical size and power performance of these critical values is good. Using the post blackened, moving block bootstrap helps to replicate the time dependencies in the original data. The Monte Carlo results show that the asymptotic critical values in Lo (1991) should not be used.
