# 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…
