On a formula for the h-index
Original language description
The h-index is a celebrated indicator widely used to assess the quality of researchers and organizations. Empirical studies support the fact that the h-index is well correlated with other simple bibliometric indicators, such as the total number of publications N and the total number of citations C . In this paper we introduce a new formula, as a representative predictive formula that relates functionally h to these aggregate indicators, N, C and the highest citation count cMAX. The formula is based on the 'specific' assumption of geometrically distributed citations, but provides a good estimate of the h-index for the general case. To empirically evaluate the adequacy of the fit of the proposed formula, an empirical study with 131 datasets (13,347 papers; 288,972 citations) was carried out. The overall fit (defined as the capacity to reproduce the true value of h, for each single scientist) was remarkably accurate. The predicted value was within one of the actual value h for more than 6
