Variation of Partition Coefficient

Nature, 1965
MATSUI and I have estimated partition coefficients for some elements1–4 and discussed the significance5,6 of estimating them. More recently7, I have estimated partition coefficients for rubidium and strontium. However, we have little knowledge about what conditions affect partition coefficients and to what extent they can be influenced. For example, it

Nonparametric Interval Estimators for the Coefficient of Variation

The International Journal of Biostatistics, 2018
Abstract The coefficient of variation (CV) is a widely used scaleless measure of variability in many disciplines. However the inference for the CV is limited to parametric methods or standard bootstrap. In this paper we propose two nonparametric methods aiming to construct confidence intervals for the coefficient of variation.

On multivariate coefficients of variation

Statistische Hefte, 1977
This paper reviews the distribution of the sample coefficient of variation (c. v.),\(v = s/\bar x\) as presented here in closed form in terms of the derivatieves of the moment generating function (m.g.f.) of the normal distribution.

Coefficient of Variation

1998
If the absolute dispersion is defined as the standard deviation, and the average is the mean, the relative dispersion is called the coefficient of variation (CV) or coefficient of dispersion. The relationship between mean and dispersion is very important in the geosciences and is expressed by the coefficient of variation according to: $$CV\% = 100 ...

The coefficient of variation biplot

Journal of Classification, 1990
This note introduces the coefficient of variation biplot, and suggests that it will provide a useful graphical display of data matrices in which the relative variability of the columns is of interest.

Variation of Fourier-Haar coefficients

Sbornik: Mathematics, 2004
Series of differences of Fourier-Haar coefficients are studied. It is demonstrated that in certain cases their behaviour is similar to the behaviour of the series of coefficients themselves.

COMMENT ON THE COEFFICIENT OF ORDINAL VARIATION

Perceptual and Motor Skills, 1995
An index of dispersion and a related standardized coefficient of variation for ordinal categorical data were recently introduced in this journal. These two measures were based on the use of category scores. In this paper, we show these measures can alternatively be expressed in terms of cumulative proportions (probabilities).

Inferences on the common coefficient of variation

Statistics in Medicine, 2005
The coefficient of variation is often used as a measure of precision and reproducibility of data in medical and biological science. This paper considers the problem of making inference about the common population coefficient of variation when it is a priori suspected that several independent samples are from populations with a common coefficient of ...

coefficient of variation (CV)

2009
standard deviation SD divided by the arithmetic mean x− and expressed as a percentage (CV (%)=SD/x− ∞?100); it permits the relative comparison of totally different sets of data (“apples vs. oranges”); → see also correlation coefficient.
