Statement from National Science Foundation (NSF) Director France Córdova regarding the news that Oliver Hart and Bengt Holmström have been awarded the 2016 Sveriges Riksbank Prize in Economic Sci...
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
microfoundations agent based models stochastic models fnancial markets 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.

Uncovering Long Memory in High Frequency UK Futures
Long Memory APARCH High Frequency Futures
2011/3/31
Accurate volatility modelling is paramount for optimal risk management practices. One stylized feature of financial volatility that impacts the modelling process is long memory explored in this paper ...
In this paper we outline initial concepts for an immune inspired algorithm to evaluate price time series data. The proposed solution evolves a short term pool of trackers dynamically through a process...
Memory effect and multifractality of cross-correlations in financial markets
Econophysics Stock market
2010/10/20
An average instantaneous cross-correlation function is introduced to quantify the interaction of the financial market of a specific time. Based on the daily data of the American and Chinese stock mark...
Scaling and memory in the return intervals of realized volatility
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...
Fractional derivatives of random walks: Time series with long-time memory
Fractional derivatives random walks Time series long-time memory
2010/12/20
We review statistical properties of models generated by the application of a (positive and negative order) fractional derivative operator to a standard random walk and show that the resulting stochas...
Scaling and Memory Effect in Volatility Return Interval of the Chinese Stock Market
Scaling Memory Effect Volatility Return Interval Chinese Stock Market
2010/12/20
We investigate the probability distribution of the volatility return intervals $\tau$ for the Chinese stock market. We rescale both the probability distribution $P_{q}(\tau)$ and the volatility return...
Return interval distribution of extreme events and long term memory
Return interval distribution extreme events long term memory
2010/12/17
The distribution of recurrence times or return intervals between extreme events is important to characterize and understand the behavior of physical systems and phenomena in many disciplines. It is we...
