On the scaling ranges of detrended fluctuation analysis for long-memory correlated short series of data
scaling range detrended fluctuation analysis Hurst exponent power laws time series long memory econophysics complex systems
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,...
Microscopic reasoning for the non-linear stochastic models of long-range memory

We extend Kirman's model by introducing variable event time scale. The proposed
exi-
ble time scale is equivalent to the variable trading activity observed in nancial markets.

Econophysics Realized volatility Return interval Scaling Long memory
2010/10/29
We performreturn interval analysis of 1-min realized volatility defined by the sum of absolute high-frequency intraday returns for the Shanghai Stock Exchange Composite Index (SSEC) and 22 constituent...
Scaling and memory in the non-poisson process of limit order cancelation
Econophysics Inter-cancelation duration Scaling Long memory Multifractal nature
2010/11/2
The order submission and cancelation processes are two crucial aspects in the price formation of stocks traded in order-driven markets. We investigate the dynamics of order cancelation by studying the...
A long-range memory stochastic model of the return in financial markets
Models of financial markets Stochastic equations Power-law distributions Long memory processes
2010/10/29
We present a nonlinear stochastic differential equation (SDE) which mimics the probability density function (PDF) of the return and the power spectrum of the ab-solute return in financial markets. Abs...
Evaluating the performance of adapting trading strategies with different memory lengths
Minority game prediction performance
2010/10/29
We propose a prediction model based on the minority game in which traders continuously evaluate a complete set of trading strategies with di erent memory lengths using the strategies' past performance...
Scaling and Memory Effect in Volatility Return Interval of the Chinese Stock Market
