Exact Probabilistic and Mathematical Proofs of the Relation between the Mean Number of Items per Source in the Bibliography and the Generalized 80/20-Rule.

Egghe, L.

Journal of the American Society for Information Science, v44 n7 p369-75 Aug 1993

Examines the 80/20 rule that relates to productive sources in a bibliography. Highlights include applications in library acquisition policies, library circulation and weeding policies, science policy studies, information science, and econometrics; formulae of Burrell and of Egghe; probabilistic proofs; geometric distributions; Lotka distribution; and mathematical proofs. (Contains 13 references.) (LRW)
