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 ...

IS THE SAMPLE COEFFICIENT OF VARIATION A GOOD ESTIMATOR FOR THE POPULATION COEFFICIENT OF VARIATION? [PDF]

, 2007
In this paper, we obtain bounds for the population coefficient of variation (CV) in Bernoulli, Discrete Uniform, Normal and Exponential distributions. We also show that the sample coefficient of variation (cv) is not an accurate estimator of the population CV in the above indicated distributions. Finally we provide some suggestions based on the Maximum

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).

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 ...

Using the Range to Calculate the Coefficient of Variation

Psychological Reports, 2004
In this research a coefficient of variation ( CVhigh-low) is calculated from the highest and lowest values in a set of data. Use of CVhigh-low when the population is normal, leptokurtic, and skewed is discussed. The statistic is the most effective when sampling from the normal distribution. With the leptokurtic distributions, CVhigh-low works well for

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

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.
