Evidence for goodness of fit in Karl Pearson chi-squared statistics
Robert G. Staudte
Chi-squared tests for lack of fit are traditionally employed to find evidence against a hypothesized model, with the model accepted if the Karl Pearson statistic comparing observed…
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…
