Insights and inference for the proportion below the relative poverty line
Dilanka S. Dedduwakumara, Luke A. Prendergast, Robert G. Staudte
We examine a commonly used relative poverty measure called the headcount ratio (), defined to be the proportion of incomes falling below the relative poverty line, which is de…
An efficient estimator of the parameters of the Generalized Lambda Distribution
Dilanka S. Dedduwakumara, Luke A. Prendergast, Robert G. Staudte
Estimation of the four generalized lambda distribution parameters is not straightforward, and available estimators that perform best have large computation times. In this paper, we…
Robust analogs to the Coefficient of Variation
Chandima N. P. G. Arachchige, Luke A. Prendergast, Robert G. Staudte
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 affe…
Decomposing the Quantile Ratio Index with applications to Australian income and wealth data
Luke A. Prendergast, Robert G. Staudte
The quantile ratio index introduced by Prendergast and Staudte 2017 is a simple and effective measure of relative inequality for income data that is resistant to outliers. It measu…
