A REVIEW ON TEMPORAL LAG CORRELATIONS IN GRBs
, 2010
"... Abstract. Gamma ray bursts (GRBs) are high energy photons detected during a short interval of time, they are signs of the most energetic events in the universe. This work is devoted to temporal lags, which reveal to be important parameters correlated to GRBs spectrum and luminosity. We perform a th ..."

Lag correlation analysis based on Boolean presentation over multiple data streams
"... Correlation analysis is a basic problem in the field of data stream mining. In this paper we propose a new method based on Boolean representation for lag correlation analysis among multiple data streams. The raw stream sequence is transformed into the Boolean sequence, and the lags in any correlatio ..."

A 6–12 GHz Analogue Lag-Correlator for Radio Interferometry
, 2006
"... Aims. We describe a 6–12 GHz analogue correlator that has been developed for use in radio interferometers. Methods. We use a lag-correlator technique to synthesis eight complex spectral channels. Two schemes were considered for sampling the cross-correlation function, using either real or complex co ..."

AutoLag: Automatic discovery of lag correlations in stream data
- In ICDE
, 2005
"... Data streams appear in multiple settings, such as environmental, medical and socioeconomic systems. There are many, fascinating research problems in such settings, like clustering [1], summarization [3], and forecasting [2]. ..."

Investor psychology and security market under- and overreactions
- Journal of Finance
, 1998
"... We propose a theory of securities market under- and overreactions based on two well-known psychological biases: investor overconfidence about the precision of private information; and biased self-attribution, which causes asymmetric shifts in investors ’ confidence as a function of their investment ..."

A Long-Memory Property of Stock Market Returns and a New Model
- Journal of Empirical Finance
, 1993
"... A ‘long memory ’ property of stock market returns is investigated in this paper. It is found that not only there is substantially more correlation between absolute returns than returns them-selves, but the power transformation of the absolute return lrfl ” also has quite high autocorrel-ation for lo ..."

Predictive regressions
- Journal of Financial Economics
, 1999
"... When a rate of return is regressed on a lagged stochastic regressor, such as a dividend yield, the regression disturbance is correlated with the regressor's innovation. The OLS estimator's "nite-sample properties, derived here, can depart substantially from the standard regression set ..."

A Dynamic Time-Lagged Correlation based Method to Learn Multi-Time Delay Gene Networks
"... Abstract—A gene network gives the knowledge of the regulatory relationships among the genes. Each gene has its activators and inhibitors that regulate its expression positively and negatively respectively. Genes themselves are believed to act as activators and inhibitors of other genes. They can eve ..."

Correlation Based Method (DTCBM) to learn the gene networks, which uses time-lagged correlation to find the potential gene interactions, and then uses a post-processing stage to remove false gene interactions to common parents, and finally uses dynamic correlation thresholds for each gene to construct
A wideband lag correlator for heterodyne spectroscopy of broad astronomical and atmospheric spectral lines
- Rev. Sci. Inst

"... WASP2 is a lag correlation spectrometer that is optimized for astronomical heterodyne observations of spectral lines from mid-infrared through centimeter wavelengths. Since the instrument is a wideband microwave spectrum analyzer, its basic technology is well suited to radio astronomy, atmospheric ..."
