Measures of dispersion are defined as functionals satisfying certain equivariance and order conditions. In the main part of the paper attention is restricted to symmetric distributions. Different ...

Most statistical indices of variability can be obtained in this way. This and a "dual" theorem also account for several measures of inequality, which are order preserving with respect to the ...

One study has introduced robust process capability indices for Weibull processes by comparing diverse measures of dispersion – such as median absolute deviation, interquartile range and Gini’s ...
