Resum
The Zipf distribution also known as scale-free distribution or discrete Pareto distribution, is the particular case of Power Law distribution with support the strictly positive integers. It is a one-parameter distribution with a linear behaviour in the log-log scale. In this paper the Zipan distribution is generalized by means of the Marshall-Olkin transformation. The new model has more exibility to adjust the probabilities of the rst positive integer numbers while keeping the linearity of the t...
