Evolution of Information Production Processes and Its Relation to the Lorenz Dominance Order.
Peer reviewed Peer reviewed
Egghe, Leo; Rousseau, Ronald – Information Processing and Management, 1993
Studies the evolution of information production processes and their relation to the Lorenz dominance order as a theoretical framework for bibliometrics. The relation between the total number of sources, the total number of items, the average production, and the maximum production are examined. Geometric illustrations are provided. (Contains 14…

Bradford Curves.
Peer reviewed Peer reviewed
Rousseau, Ronald – Information Processing and Management, 1994
Discussion of informetric distributions shows that generalized Leimkuhler functions give proper fits to a large variety of Bradford curves, including those exhibiting a Groos droop or a rising tail. The Kolmogorov-Smirnov test is used to test goodness of fit, and least-square fits are compared with Egghe's method. (Contains 53 references.) (LRW)
