The performance of modularity maximization in practical contexts (2009)
Good, Benjamin H., De Montjoye, Yves-Alexandre, Clauset, Aaron
Although widely used in practice, the behavior and accuracy of the popular module identification technique called modularity maximization is not well understood. Here, we present a broad and...

Aaron Clauset, David J. Schwab, Sidney Redner
Within large taxonomic assemblages, the number of species with adult body mass M is characterized by a broad but asymmetric distribution, with the largest mass being orders of magnitude larger than...
The developmental dynamics of terrorist organizations (2009)
Clauset, Aaron, Gleditsch, Kristian Skrede

A generalized fission-fusion model for the frequency of severe terrorist attacks (2009)
Clauset, Aaron, Wiegel, Frederik W.
We present and analyze a model of the frequency of severe terrorist attacks, which generalizes the recently proposed model of Johnson et al. This model, which is based on the notion of...
We test the claim by Yu et al. -- presented in Science 322, 104 (2008) -- that the degree distribution of the yeast (Saccharomyces cerevisiae) protein-interaction network is best approximated by a...
The evolution and distribution of species body size (2009)

Strategic Substitution and Complimentarity in the Israel-Palestine Conflict (2008)
Aaron Clauset, Lindsay Heger, Maxwell Young, Kristian Skrede Gleditsch
Terrorism is one of many possible tactics to which actors may resort in political conflicts; however, previous studies of the strategic substitution within terrorism have primarily focused on shifts...
Hierarchical structure and the prediction of missing links in networks (2008)
Clauset, Aaron, Moore, Cristopher, Newman, M. E. J.
Networks have in recent years emerged as an invaluable tool for describing and quantifying complex systems in many branches of science. Recent studies suggest that networks often exhibit hierarchical...
Evolutionary Model of Species Body Mass Diversification (2008)
Clauset, Aaron, Redner, Sidney
We present a quantitative model for the biological evolution of species body masses within large groups of related species, e.g., terrestrial mammals, in which body mass M evolves according to...
How many species have mass M? (2008)
Clauset, Aaron, Schwab, David J., Redner, Sidney
Within large taxonomic assemblages, the number of species with adult body mass M is characterized by a broad but asymmetric distribution, with the largest mass being orders of magnitude larger than...
Hierarchical structure and the prediction of missing links in networks (2008)
Clauset, Aaron, Moore, Cristopher, Newman, M. E. J.
Networks have in recent years emerged as an invaluable tool for describing and quantifying complex systems in many branches of science(1-3). Recent studies suggest that networks often exhibit...
Structural Inference of Hierarchies in Networks (2008)
One property of networks that has received comparatively little attention is hierarchy, i.e., the property of having vertices that cluster together in groups, which then join to form groups of...
Power-law distributions in empirical data (2007)
Clauset, Aaron, Shalizi, Cosma Rohilla, Newman, M. E. J.
Power-law distributions occur in many situations of scientific interest and have significant consequences for our understanding of natural and man-made phenomena. Unfortunately, the detection and...
Structural Inference of Hierarchies in Networks (2006)
Clauset, Aaron, Moore, Cristopher, Newman, M. E. J.
One property of networks that has received comparatively little attention is hierarchy, i.e., the property of having vertices that cluster together in groups, which then join to form groups of...
On the Frequency of Severe Terrorist Events (2006)
Clauset, Aaron, Young, Maxwell, Gleditsch, Kristian Skrede
In the spirit of Richardson's original (1948) study of the statistics of deadly conflicts, we study the frequency and severity of terrorist attacks worldwide since 1968. We show that these events are...

Scale Invariance in Road Networks (2005)
Kalapala, Vamsi, Sanwalani, Vishal, Clauset, Aaron, Moore, Cristopher
We study the topological and geographic structure of the national road networks of the United States, England and Denmark. By transforming these networks into their dual representation, where roads...
Finding local community structure in networks (2005)
Although the inference of global community structure in networks has recently become a topic of great interest in the physics community, all such algorithms require that the graph be completely...
On the Bias of Traceroute Sampling; or, Power-law Degree Distributions in Regular Graphs (2005)
