Equivalent Gini coefficient, not shape parameter!

Abstract

In a recent contribution in this journal, Gagolewski et al. (Scientometrics 127(5):2829–2845, 2022) study a new model—the so-called 3 dimensions of scientific impact (3DSI) model—for representing a rank size distribution. The model depends on three parameters/dimensions: the total number of papers, the total number of citations and a third parameter, $$\rho$$ ρ , recognized by the authors as a shape parameter. We prove that $$\rho$$ ρ is an equivalent Gini coefficient.
