Zipf extensions and their applications for modeling the degree sequences of real networks

Ariel Duarte López

Abstract: The Zipf distribution, also known as discrete Pareto distribution, attracts considerable attention because it helps describe skewed data from many natural as well as man-made systems. Under the Zipf distribution, the frequency of a given value is a power function of its size. Consequently, when plotting the frequencies versus the size in log-log scale for data following this distribution, one obtains a straight line. Nevertheless, for many data sets the linearity is only observed in the tail and when this happ… Show more

“… NUM_OF_REQUESTS_PER_SESSION is the number of requests that are generated in each session, which is set to be 500,000 requests per session.  AlphaSet is the set of alphas that is used by the Zipf distribution [18] to create the object popularity for each session. The alpha values for the six intervals are set as the following: [0.8, 1.0, 0.5, 0.7, 1.2, and 0.6].…”
