zipfextR - Zipf Extended Distributions
Implementation of four extensions of the Zipf
distribution: the Marshall-Olkin Extended Zipf (MOEZipf)
PĂ©rez-Casany, M., & Casellas, A. (2013) <arXiv:1304.4540>, the
Zipf-Poisson Extreme (Zipf-PE), the Zipf-Poisson Stopped Sum
(Zipf-PSS) and the Zipf-Polylog distributions. In log-log
scale, the two first extensions allow for top-concavity and
top-convexity while the third one only allows for
top-concavity. All the extensions maintain the linearity
associated with the Zipf model in the tail.
