| Abstract | The purpose of this study was to develop a model for the distribution of authorships--based on the initial hypothesis that the distribution of authorships follows a shifted Waring distribution--and to test the derived model and some other discrete probability models for goodness-of-fit against empirical data. Bibliographic data from 15 abstracting journals covering the literature in six fields--engineering, medical, physical, mathematical and social sciences, and humanities--were used in testing the goodness-of-fit of the shifted Waring distribution and 13 other discrete probability models. The preliminary findings presented here are based on 60 data sets collected from 10 abstracting journals covering the literature in the mathematical and social sciences and humanities. They indicate that the promising models for the distribution of authorships are the shifted Waring, shifted generalized negative binomial, shifted negative binomial, shifted generalized Poisson, and shifted inverse Gaussian-Poisson distributions. Three advantages and possible practical applications of a model for the distribution of authorships include: (1) ability to summarize the entire frequency distribution by a few parameters of the model; (2) estimation of the number of entries in an author index; and (3) usefulness in a simulation study designed to determine, subject to space constraints, the maximum number of authors per paper to be included in an author index. Forms of the discrete probability models are appended. (5 tables, 12 references) (Author/CGD) |
