Title: | New Bradfordian laws equivalent with old Lotka, evolving from a source-item argument | Authors: | EGGHE, Leo | Issue Date: | 1990 | Publisher: | Elsevier | Source: | Egghe, L. & Rousseau, R. (Ed.) Informetrics 89/90, Belgium : Diepenbeek, p.79-96 | Abstract: | Based on the duality techniques in a previous paper (L. Egghe, The duality o f informetric systems with applications to the empirical laws), we study general relationships between Bradfordian and Lotka laws. This results in new Bradfordian laws which are B equivalent with the well-known Lotka laws $(n) = - (a > 1). The new method also sheds some light on the question why a < 2 i s more common than a > 2. Also, the general law of Leimkuhler, as found by Rousseau, i s reproved and shown to be equivalent with the above mentioned laws. Fitting methods are applied and give close results. | Document URI: | http://hdl.handle.net/1942/854 | Type: | Proceedings Paper |
