On the coefficient of variation of the - and -classes
Statistics & Probability Letters, 1996Abstract The coefficient of variation of a life distribution is no more than 1 if it belongs to the L -class and no less than 1 if it belongs to the L -class. However, there are nonexponential distributions in each of these classes that have coefficient of variation equal to 1.

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 ...

Inferences on the common coefficient of variation
Statistics in Medicine, 2005The 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 ...

COMMENT ON THE COEFFICIENT OF ORDINAL VARIATION
Perceptual and Motor Skills, 1995An 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).

Using the Range to Calculate the Coefficient of Variation
Psychological Reports, 2004In this research a coefficient of variation ( CV high-low ) is calculated from the highest and lowest values in a set of data. Use of CV high-low when the population is normal, leptokurtic, and skewed is discussed.

Variation of Partition Coefficient
Nature, 1965MATSUI 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

On multivariate coefficients of variation
Statistische Hefte, 1977This 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.
