On the Correlation Between Correlations
Biometrika, 1975Specific tests for the equality of two dependent interclass correlations, estimated from a multivariate sample, have been examined in some detail by Dunn & Clark (1969, 1971). In this paper I wish to consider the dependencies among correlation coefficients in more generality, whether interclass or intraclass, and hence to suggest appropriate large ...

Magnetic Resonance in Medicine, 1991
AbstractCalculations and experiments that provide support for our previously stated theorem are presented: If two coils simultaneously receiving magnetic resonance signals from the same anatomic region exhibit zero mutual inductance, there can be no correlation of the noise.

Physical Review E, 1999
The fact that correlation does not imply causation is well known. Correlation between variables at two sites does not imply that the two sites directly interact, because, e.g., correlation between distant sites may be induced by chaining of correlation between a set of intervening, directly interacting sites.

Psychometrika, 1984
A correlational measure for an n by p matrix X and an n by q matrix Y assesses their relation without specifying either as a fixed target. This paper discusses a number of useful measures of correlation, with emphasis on measures which are invariant with respect to rotations or changes in singular values of either matrix.

Summary: The main point of this note is to give a simple semigroup proof of a correlation inequality due to \textit{Y. Hu} [``Note on correlation and covariance inequalities'' (Preprint, 1995)]. We also recover recent correlation inequalities due to \textit{C. Houdré}, \textit{V. Pérez-Abreu} and \textit{D. Surgailis} [J. Fourier Anal. Appl. 4, No.

The correlations between positions of particles in classical equilibrium statistical mechanics are usually expressed by correlation functions. It can be seen that if the correlation functions of a system are known, its configurational entropy per unit volume is already determined (independently of the interaction potential or other thermodynamical ...

Correlative microscopy is a method when for the analysis of the very same cell or tissue area several different methods of light or electron microscopy are used. Usually these methods of analysis are separated by the period of additional preparation. Traditionally, LM and EM observations are carried out in different populations of cells/tissues.

Australian Critical Care, 2012
A common question of interest in nursing research is the relationships between variables. Correlational analysis is a statistical technique employed to investigate the magnitude and significance of such relationships. This paper presents commonly used techniques to examine bivariate relationships of interval/ratio, ordinal and nominal variables.
