Abstract: This paper examines the properties of the Gini coefficient estimator for gamma mixture populations and reveals the presence of bias. In contrast, we show that sampling from a gamma distribution yields an unbiased estimator, consistent… read more here.

Abstract: Parametric family of statistical distributions are of great importance for several applications. In particular, we propose to investigate the generalized Gamma mixture model ( $\text{g}\Gamma $ MM) for modeling and classifying medical imaging (Chest x-ray… read more here.
