Statistical methods in information science, Weibull distribution, Power law (Mathematics), Pareto analysis, and Mathematics
Based on three theorems for size-to-rank transformations, the shifted power function is used to set up a theoretical framework unifying informetric distributions. While the shifted power function with time-type exponential cutoff supplies a unifying informetric framework, the shifted power function with space-type exponential cutoff can be linked to the Pareto and Weibull distributions. The exponent is the crucial parameter in a power function, determining the most important characteristics of the power-law distribution. [ABSTRACT FROM AUTHOR]
