High p_T Hadron Correlation and No Correlation [PDF]

open access: yesNuclear Physics A, 2006
An overview of the correlation among high-p_T hadrons produced in heavy-ion collisions is presented. Emphasis is placed on the physical processes that can quantitatively account for the data on correlations in p_T, \eta and \phi on the near and far sides.

Correlations for computation and computation for correlations [PDF]

open access: yesnpj Quantum Information, 2021
AbstractQuantum correlations are central to the foundations of quantum physics and form the basis of quantum technologies. Here, our goal is to connect quantum correlations and computation: using quantum correlations as a resource for computation—and vice versa, using computation to test quantum correlations.

Correlations [PDF]

open access: yesSSRN Electronic Journal, 2009
Correlations of equity returns have varied substantially over time and remain a source of continuing policy debate. This paper studies stock market correlations in an equilibrium model with heterogeneous risk aversion. In the model, preference heterogeneity causes variations in the volatility of aggregate risk aversion from good to bad states.

Correlation scenarios and correlation stress testing [PDF]

open access: yesSSRN Electronic Journal, 2021
We develop a general approach for stress testing correlations of financial asset portfolios. The correlation matrix of asset returns is specified in a parametric form, where correlations are represented as a function of risk factors, such as country and industry factors.

Correlation Coefficients: Appropriate Use and Interpretation

open access: yesAnesthesia and Analgesia, 2018
Correlation in the broadest sense is a measure of an association between variables. In correlated data, the change in the magnitude of 1 variable is associated with a change in the magnitude of another variable, either in the same (positive correlation ...
