# Test of two hypotheses explaining the size of populations in a system of cities

@article{Vitanov2015TestOT, title={Test of two hypotheses explaining the size of populations in a system of cities}, author={Nikolay K. Vitanov and Marcel Ausloos}, journal={Journal of Applied Statistics}, year={2015}, volume={42}, pages={2686 - 2693} }

Two classical hypotheses are examined about the population growth in a system of cities: Hypothesis 1 pertains to Gibrat's and Zipf's theory which states that the city growth–decay process is size independent; Hypothesis 2 pertains to the so-called Yule process which states that the growth of populations in cities happens when (i) the distribution of the city population initial size obeys a log-normal function, (ii) the growth of the settlements follows a stochastic process. The basis for the… Expand

Zipf’s law and city size distribution: A survey of the literature and future research agenda

- Economics
- 2018

Abstract This study provides a systematic review of the existing literature on Zipf’s law for city size distribution. Existing empirical evidence suggests that Zipf’s law is not always observable… Expand

Population patterns in World’s administrative units

- Mathematics, Physics
- Royal Society Open Science
- 2017

This work investigates the population distribution of second-level administrative units of 150 countries and territories and proposes the discrete generalized beta distribution (DGBD) rank-size function, which is a good statistical model for 96% of datasets and preferred over a power law in almost every case.

ABSTRACT In this paper, we propose that relations between high-order moments of data distributions, for example, between the skewness (S) and kurtosis (K), allow to point to theoretical models with… Expand

On the Mathematical Theory of Human Migration: Model of a Migration Channel with a Secondary and a Tertiary Arm

- Mathematics, Physics
