Comparing correlated correlation coefficients.

Psychological Bulletin, 1992
The purpose of this article is to provide simple but accurate methods for comparing correlation coefficients between a dependent variable and a set of independent variables. The methods are simple extensions of Dunn & Clark's (1969) work using the Fisher z transformation and include a test and confidence interval for comparing two correlated ...

The Polyserial Correlation Coefficient

Psychometrika, 1982
The polyserial and point polyserial correlations are discussed as generalizations of the biserial and point biserial correlations. The relationship between the polyserial and point polyserial correlation is derived. The maximum likelihood estimator of the polyserial correlation is compared with a two-step estimator and with a computationally convenient

On the Maximum Correlation Coefficient

Theory of Probability & Its Applications, 2005
Summary: For an arbitrary random vector \((X,Y)\) and an independent random variable \(Z\) it is shown that the maximum correlation coefficient between \(X\) and \(Y+\lambda Z\) as a function of \(\lambda\) is lower semicontinuous everywhere and continuous at zero where it attains its maximum.

Range of Correlation Coefficients

Psychological Reports, 1968
A single correlation coefficient can take values between −1.0 and +1.0. What is just as important, but less often taught, is that the correlations in a matrix of intercorrelations are not free to vary over the same range of values. This is relevant whenever we try to assess whether a number of variables have relatively high or relatively low ...

Spectral Coefficients and Classifier Correlation

2003
Various counting measures, such as Margin and Bias/ Variance, have been proposed for analysing Multiple Classifier Systems (MCS) performance. In this paper a measure based on counting votes to estimate first order spectral coefficients for two-class problems is described.

Coefficient of correlation

1975
By plotting a scatter diagram we can see at a glance whether or not a relationship exists between two variables.
