متن کاملEmpirical modeling of the impact factor distribution
The distribution of impact factors has been modeled in the recent informetric literature using twoexponent law proposed by Mansilla et al. (2007). This paper shows that two distributions widelyused in economics, namely the Dagum and Singh-Maddala models, possess several advantages over the two-exponent model. Compared to the latter, the former give as good as or slightly better fit to data on i...
