NEW CORRELATION COEFFICIENT FOR DATA ANALYSIS [PDF]

open access: yesScientific Papers Series : Management, Economic Engineering in Agriculture and Rural Development, 2012
The proposed correlation coefficient better characterize the statistical independence of two random variables that are a linear mixture of two independent sources. This correlation coefficient can be calculated with analytical relations or with the known

A Modification of Linfoot's Informational Correlation Coefficient

open access: yesAustrian Journal of Statistics, 2017
Performance of the Linfoot's informational correlation coefficient is experimentally studied at the bivariate normal distribution. It is satisfactory in the case of a strong correlation and on large samples.

On asymptotic correlation coefficient for some order statistics

open access: yesAIMS Mathematics, 2023
By the relationship between a continuous population X and the uniform distribution U[0,1], we gain for a sample quantile an equivalent expression of its variance and for two different sample quantiles the asymptotic correlation coefficient.

A cophenetic correlation coefficient for Tocher's method

open access: yesPesquisa Agropecuária Brasileira, 2013
The objective of this work was to propose a way of using the Tocher's method of clustering to obtain a matrix similar to the cophenetic one obtained for hierarchical methods, which would allow the calculation of a cophenetic correlation.

Detecting pairwise correlations in spike trains: an objective comparison of methods and application to the study of retinal waves. [PDF]

open access: yes, 2014
Correlations in neuronal spike times are thought to be key to processing in many neural systems. Many measures have been proposed to summarize these correlations and of these the correlation index is widely used and is the standard in studies of ...

SLE_k: correlation functions in the coefficient problem

open access: yes, 2012
We apply the method of correlation functions to the coefficient problem in stochastic geometry. In particular, we give a proof for some universal patterns conjectured by M.
