2012/9/14
We examine the scaling regime for the detrended fluctuation analysis (DFA) -the most popular method used to detect the presence of long memory in data and
the fractal structure of time series. First,...
Rescaled Range Analysis and Detrended Fluctuation Analysis: Finite Sample Properties and Confidence Intervals
Rescaled range analysis detrended fluctuation analysis Hurst exponent
2010/12/6
We focus on finite sample properties of two mostly used methods of Hurst exponent H estimation—rescaled range analysis (R/S) and detrended fluctuation analysis (DFA). Even though both methods have bee...
Modified detrended fluctuation analysis based on empirical mode decomposition
Modified detrended empirical mode decomposition
2010/11/1
Detrended fluctuation analysis (DFA) is a simple but very efficient method for investigating
the power-law long-term correlations of non-stationary time series, in which a detrending step is necessar...

Detrended fluctuation analysis intertrade durations
2010/12/20
The intraday pattern, long memory, and multifractal nature of the intertrade durations, which are defined as the waiting times between two consecutive transactions, are investigated based upon the li...
