Title: | The influence of missing publications on the Hirsch index | Authors: | ROUSSEAU, Ronald | Issue Date: | 2007 | Publisher: | ELSEVIER SCIENCE BV | Source: | JOURNAL OF INFORMETRICS, 1(1). p. 2-7 | Abstract: | We show that usually the influence on the Hirsch index of missing highly cited articles is much smaller than the number of missing articles. This statement is shown by a combinatorial argument. We further show, by using a continuous power law model, that the influence of missing articles is largest when the total number of publications is small, and non-existing when the number of publications is very large. The same conclusion can be drawn for missing citations. Hence, the h-index is resilient to missing articles and to missing citations. (c) 2006 Elsevier Ltd.
