Kramers escape rate in overdamped systems with the power-law distribution [PDF]

open access: yes, 2014
Kramers escape rate in the overdamped systems is restudied for the power-law distribution. By using the mean first passage time, we derive the escape rate with the power-law distribution and obtain the Kramers’ infinite barrier escape rate in this case ...

Time-varying volatility and the power law distribution of stock returns

open access: yesJournal of Empirical Finance, 2016
While many studies find that the tail distribution of high frequency stock returns follow a power law, there are only a few explanations for this finding. This study presents evidence that time-varying volatility can account for the power law property of

The invariances of power law size distributions [PDF]

open access: yesF1000Research, 2016
Size varies. Small things are typically more frequent than large things. The logarithm of frequency often declines linearly with the logarithm of size. That power law relation forms one of the common patterns of nature. Why does the complexity of nature reduce to such a simple pattern?

Examining the power-law distribution among eWOM communities: a characterisation approach of the Long Tail

open access: yesTechnology Analysis & Strategic Management, 2016
Nowadays electronic word-of-mouth (eWOM) communities symbolise a significant source of information that helps customers to make informed purchasing decisions.

Escape rate for the power-law distribution in low-to-intermediate damping [PDF]

open access: yes, 2014
Escape rate in the low-to-intermediate damping connecting the low damping with the intermediate damping is established for the power-law distribution on the basis of flux over population theory.

Power-law Distribution Aware Trust Prediction [PDF]

open access: yesProceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence, 2018
Trust prediction, aiming to predict the trust relations between users in a social network, is a key to helping users discover the reliable information. Many trust prediction methods are proposed based on the low-rank assumption of a trust network.

Taylor’s power law for the N-stars network evolution model

open access: yesModern Stochastics: Theory and Applications, 2019
Taylor’s power law states that the variance function decays as a power law. It is observed for population densities of species in ecology. For random networks another power law, that is, the power law degree distribution is widely studied.

Fitting Heavy Tailed Distributions: The poweRlaw Package

open access: yesJournal of Statistical Software, 2015
Over the last few years, the power law distribution has been used as the data generating mechanism in many disparate fields. However, at times the techniques used to fit the power law distribution have been inappropriate.

Power-law Distribution of Solar Cycle–modulated Coronal Jets

open access: yesThe Astrophysical Journal Supplement Series, 2023
Power-law distributions have been studied as a significant characteristic of nonlinear dissipative systems. Since discovering the power-law distribution of solar flares that was later extended to nanoflares and stellar flares, it has been widely accepted
