Pratt's Measure for Some Bibliometric Distributions and Its Relation with the 80/20 Rule.

Egghe, L.

Journal of the American Society for Information Science, v38 n4 p288-97 Jul 1987

Pratt's measure C on the class concentration of bibliometric distributions is calculated and interpreted for the laws of Zipf, Mandelbrot, and Lotka and geometric distribution, and comparisons are made of the results. An explicit mathematical formula which unifies disparate theories is derived and tested. (Author/CLB)
