Power-law stellar distributions [PDF]
Physica A: Statistical Mechanics and its Applications, 2005 The density profiles and other quantities of physical interest for spherically symmetric systems are computed by assuming that a collisionless stellar gas may relax to the non-Gaussian power law distribution suggested by the nonextensive kinetic theory. There are two different classes of solutions.

Power law distributions in class relationships [PDF]
Proceedings Third IEEE International Workshop on Source Code Analysis and Manipulation, 2004 Power law distributions have been found in many natural and social phenomena, and more recently in the source code and run-time characteristics of Object-Oriented (OO) systems. A power law implies that small values are extremely common, whereas large values are extremely rare.

Gibbsian Theory of Power-Law Distributions [PDF]
Physical Review Letters, 2008 It is shown that power law phase space distributions describe marginally stable Gibbsian equilibria far from thermal equilibrium which are expected to occur in collisionless plasmas containing fully developed quasi-stationary turbulence. Gibbsian theory is extended on the fundamental level to statistically dependent subsystems introducing an `ordering ...

Power Laws Distributions in Objective Priors
Statistica Sinica, 2023 The use of objective prior in Bayesian applications has become a common practice to analyze data without subjective information. Formal rules usually obtain these priors distributions, and the data provide the dominant information in the posterior distribution. However, these priors are typically improper and may lead to improper posterior.

Actor-Level Dynamicity: Its Distribution Analysis Eases Anomaly Detection in Longitudinal Networks
IEEE Access, 2019 Different distributions have been observed across a wide variety of physical, biological, and man-made phenomena. For example, human height and blood pressure follow a normal distribution.

Problems with fitting to the power-law distribution [PDF]
The European Physical Journal B, 2004 This short communication uses a simple experiment to show that fitting to a power law distribution by using graphical methods based on linear fit on the log-log scale is biased and inaccurate. It shows that using maximum likelihood estimation (MLE) is far more robust.

On reconciling disparate studies of the sea-ice floe size distribution
Elementa: Science of the Anthropocene, 2018 The size distribution of sea-ice floes is an important descriptor of the sea-ice cover. Most studies report that floe sizes follow a power-law distribution over some size range, but the power-law exponents often differ substantially. Other studies report

Power-Law Tail Distributions and Nonergodicity [PDF]
Physical Review Letters, 2004 We establish an explicit correspondence between ergodicity breaking in a system described by power-law tail distributions and the divergence of the moments of these distributions.
