Exact finite-sample bias, variance, and MSE of normalized scale-invariant inequality indices under Gamma mixture models
Roberto Vila, Felipe Quintino
We study the finite-sample properties of estimators of a broad class of normalized scale-invariant inequality indices (NSIIs) under finite Gamma mixture models. The class includes…

A general class of continuous asymmetric distributions with positive support
Felipe S. Quintino, Pushpa N. Rathie, Luan C. S. M. Ozelim +2
In order to better fit real-world datasets, studying asymmetric distribution is of great interest. In this work, we derive several mathematical properties of a general class of asy…
