PAFit: A Statistical Method for Measuring Preferential Attachment in Temporal Complex Networks
- Computer SciencePloS one
- 2015
PAFit constitutes an advance over previous methods primarily because it based it on a nonparametric statistical framework that enables attachment kernel estimation free of any assumptions about its functional form, and it is found that the application of PAFit to a publically available Flickr social network dataset yielded clear evidence for a deviation of the attachment kernel from the popularly assumed log-linear form.
PAFit: An R Package for the Non-Parametric Estimation of Preferential Attachment and Node Fitness in Temporal Complex Networks
- Computer Science

The R package PAFit is introduced, which implements non-parametric procedures for estimating the preferential attachment function and node fitnesses in a growing network, as well as a number of functions for generating complex networks from these two mechanisms.

This work introduces a Bayesian statistical method called PAFit to estimate preferential attachment and node fitness without imposing such functional constraints that works by maximizing a log-likelihood function with suitably added regularization terms.
Measuring preferential attachment for evolving networks

Measurements on four networks indicate that the rate at which nodes acquire links depends on the node's degree, offering direct quantitative support for the presence of preferential attachment.

The results suggest the co-authorship and citation temporal networks are governed by both the fit get richer and the rich get richer processes.

It was found that on average, while the veterans tend to be more competent at developing new collaborations, the newcomers are likely better at acquiring new citations and coupling node fitnesses throughout different networks might be a promising new direction in analyzing simultaneously multiple networks.

It is shown that to explain the growth of the citation network by preferential attachment, one has to accept that individual nodes exhibit heterogeneous fitness values that decay with time, which makes the model an apt candidate for modeling a wide range of real systems.

Three collaboration modes that correspond to three distinct ranges in the distribution of collaborators are found, and it is found that authors with between 250 and 800 collaborators are more frequent than expected because of the hyperauthorship practices in certain subfields.
