Universality of kappa distributions
Europhysics LettersThis paper reveals the universality of the particle energy distribution function, despite the arbitrariness that characterizes the generalized thermodynamic entropic function.

Penalized likelihood approach for the four-parameter kappa distribution. [PDF]
J Appl Stat, 2022 The four-parameter kappa distribution (K4D) is a generalized form of some commonly used distributions such as generalized logistic, generalized Pareto, generalized Gumbel, and generalized extreme value (GEV) distributions. Owing to its flexibility, the K4D is widely applied in modeling in several fields such as hydrology and climatic change.

The disagreeable behaviour of the kappa statistic
Pharmaceutical Statistics, 2015 It is often of interest to measure the agreement between a number of raters when an outcome is nominal or ordinal. The kappa statistic is used as a measure of agreement. The statistic is highly sensitive to the distribution of the marginal totals and can

Correlations and Kappa Distributions: Numerical Experiment and Physical Understanding
EntropyKappa distributions, their statistical framework, and their thermodynamic origin describe systems with correlations among their particle energies, residing in stationary states out of classical thermal equilibrium/space plasmas, from solar wind to the ...

Exploring Numerical Correlations: Models and Thermodynamic Kappa
EntropyMcComas et al. (2025) introduced a numerical experiment, where ordinary uncorrelated collisions between collision pairs are followed by other, controlled (correlated) collisions, shedding light on the emergence of kappa distributions through particle ...

Scalings for the Alfvén-cyclotron instability in a bi-kappa plasma
Earth and Planetary Physics, 2023 The particle velocity distribution in space plasma usually exhibits a non-Maxwellian high-energy tail that can be well modeled by kappa distributions.

Dissipative Ion-Acoustic Solitary Waves in Magnetized κ-Distributed Non-Maxwellian Plasmas
Physics, 2022 The propagation of dissipative electrostatic (ion-acoustic) solitary waves in a magnetized plasma with trapped electrons is considered via the Schamel formalism.

Entropy, 2023 The effects of nonextensive electrons on nonlinear ion acoustic waves in dusty negative ion plasmas with ion–dust collisions are investigated. Analytical results show that both solitary and shock waves are supported in this system.

The $\kappa$-generalised Distribution for Stock Returns
Empirical evidence shows stock returns are often heavy-tailed rather than normally distributed. The $\kappa$-generalised distribution, originated in the context of statistical physics by Kaniadakis, is characterised by the $\kappa$-exponential function ...

Relativistic regularized kappa distributions [PDF]
Physics of Plasmas, 2022 The special relativistic generalization of isotropic regularized kappa distributions is derived and compared to that of the original Olbertian (or standard) kappa distributions. It is demonstrated that for the latter, the kappa parameter is even more strongly limited than in the non-relativistic case, while for the former, all positive kappa values ...
