Time window to constrain the corner value of the global seismic-moment distribution
Alvaro Corral, Isabel Serra
It is well accepted that, at the global scale, the Gutenberg-Richter (GR) law describing the distribution of earthquake magnitude or seismic moment has to be modified at the tail t…
The distinct flavors of Zipf's law in the rank-size and in the size-distribution representations, and its maximum-likelihood fitting
Alvaro Corral, Isabel Serra, Ramon Ferrer-i-Cancho
In the last years, researchers have realized the difficulties of fitting power-law distributions properly. These difficulties are higher in Zipf's systems, due to the discreteness…
Universality of power-law exponents by means of maximum likelihood estimation
Víctor Navas-Portella, Álvaro González, Isabel Serra +2
Power-law type distributions are extensively found when studying the behaviour of many complex systems. However, due to limitations in data acquisition, empirical datasets often on…
Comment on "Rényi entropy yields artifficial biases not in the data and incorrect updating due to the infinite-size data"
Petr Jizba, Jan Korbel
In their recent paper [Phys. Rev. E 99 (2019) 032134], T. Oikinomou and B. Bagci have argued that Rényi entropy is ill-suited for inference purposes because it is not consistent wi…
