Robust analogs to the coefficient of variation

CNPG Arachchige, LA Prendergast… - Journal of Applied …, 2022 - Taylor & Francis
The coefficient of variation (CV) is commonly used to measure relative dispersion. However,
since it is based on the sample mean and standard deviation, outliers can adversely affect it …

quantile density. The optimal bandwidth for kernel estimation of the quantile density …

The shapes of things to come: Probability density quantiles

RG Staudte - Statistics, 2017 - Taylor & Francis
For every discrete or continuous location-scale family having a square-integrable density,
there is a unique continuous probability distribution on the unit interval that is determined by …

An efficient estimator of the parameters of the generalized lambda distribution

DS Dedduwakumara, LA Prendergast… - Journal of Statistical …, 2021 - Taylor & Francis
Estimation of the four generalized lambda distribution parameters is not straightforward, and
