The Luminosity and Color Dependence of the Galaxy Correlation Function [PDF]

open access: yes, 2004
We study the luminosity and color dependence of the galaxy two-point correlation function in the Sloan Digital Sky Survey, starting from a sample of ~200,000 galaxies over 2500 deg2.

Tailored quantum statistics from broadband states of light

open access: yesNew Journal of Physics, 2015
We analyze the statistics of photons originating from amplified spontaneous emission generated by a quantum dot superluminescent diode. Experimentally detectable emission properties are taken into account by parametrizing the corresponding quantum state ...

Boundary correlation function of fixed-to-free bcc operators in square-lattice Ising model

open access: yes, 2006
We calculate the boundary correlation function of fixed-to-free boundary condition changing operators in the square-lattice Ising model. The correlation function is expressed in four different ways using $2\times2$ block Toeplitz determinants.

Spearman’s rank correlation coefficient

open access: yesBritish medical journal, 2018
(Redirected from Spearman's rho) In statistics, Spearman's rank correlation coefficient, named after Charles Spearman and often denoted by the Greek letter ρ (rho), is a non-parametric measure of correlation – that is, it assesses how well an arbitrary ...

Correlation function for a periodic box-ball system

open access: yes, 2009
We investigate correlation functions in a periodic box-ball system. For the two point functions of short distance, we give explicit formulae obtained by combinatorial methods.

The intensity correlation function of "blinking" quantum systems

open access: yes, 2002
Explicit expressions are determined for the photon correlation function of ``blinking'' quantum systems, i.e. systems with different types of fluorescent periods.

Correlation and regression

open access: yesStatistics at Square One, 2019
and asked them to mentally refold the cube with the shaded square on the bottom to determine if the two arrows came together. Shepard and Feng told the participants to do this as quickly and as accurately as possible.

Compactly Supported Correlation Functions

open access: yesJournal of Multivariate Analysis, 2002
This article proposes compactly supported correlation functions, which parameterize the smoothness of the associated stationary and isotropic random field. The constructions are straightforward, and compact support is relevant for various ends: computationally efficient spatial prediction, fast and exact simulation, and appeal among practitioners.

Quantum dynamical correlations: Effective potential analytic continuation approach

open access: yes, 2003
We propose a new quantum dynamics method called the effective potential analytic continuation (EPAC) to calculate the real time quantum correlation functions at finite temperature.

Scaling Dynamical Correlation Energy from Density Functional Theory Correlation Functionals [PDF]

open access: yesThe Journal of Physical Chemistry A, 2005
The scaling of dynamical correlation energy in molecules obtained by the correlation functionals of density functional theory (DFT) is examined. The approach taken is very similar to the scaled external correlation method of Brown and Truhlar but is based on the observation that DFT correlation functionals, especially the LYP, appear to represent the ...
