The size distribution of US cities: Not Pareto, even in the tail
We question the claim that the largest US cities are Pareto distributed. We show that results of multiple tests on real data are similar to those obtainedwhen the true distribution is lognormal, and largely depend on sample sizes. © 2013 Elsevier B.V. All rights reserved.
متن کاملThe Double Pareto-Lognormal Distribution – A New Parametric Model for Size Distributions
A family of probability densities, which has proved useful in modelling the size distributions of various phenomena, including incomes and earnings, human settlement sizes, oil-field volumes and particle sizes, is introduced. The distribution, named herein as the double Pareto-lognormal or dPlN distribution, arises as that of the state of a geometric Brownian motion (GBM), with lognormally dist...
متن کاملLognormal and Pareto distributions in the Internet
Numerous studies have reported long-tailed distributions for various network metrics, including file sizes, transfer times, and burst lengths. We review techniques for identifying long-tailed distributions based on a sample, propose a new technique, and apply these methods to datasets used in previous reports. We find that the evidence for long tails is inconsistent, and that lognormal and othe...
متن کاملThe exponential age distribution and the Pareto firm size distribution
Recent work drawing on data for large and small firms has shown a Pareto distribution of firm size. We mix a Gibrat-type growth process among incumbents with an exponential distribution of firm’s age, to obtain the empirical Pareto distribution. JEL codes: L20, L25
متن کاملPacking fraction of particles with lognormal size distribution.
This paper addresses the packing and void fraction of polydisperse particles with a lognormal size distribution. It is demonstrated that a binomial particle size distribution can be transformed into a continuous particle-size distribution of the lognormal type. Furthermore, an original and exact expression is derived that predicts the packing fraction of mixtures of particles with a lognormal d...
