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…
Interval estimators for inequality measures using grouped data
Dilanka S. Dedduwakumara, Luke A. Prendergast
Income inequality measures are often used as an indication of economic health. How to obtain reliable confidence intervals for these measures based on sampled data has been studied…
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…
Confidence Intervals for Quantiles from Histograms and Other Grouped Data
Dilanka S. Dedduwakumara, Luke A. Prendergast
Interval estimation of quantiles has been treated by many in the literature. However, to the best of our knowledge there has been no consideration for interval estimation when the…
