An alternative to the Cauchy distribution [PDF]

open access: yesMethodsX, 2019
A few generalizations of the Cauchy distribution appear in the literature. In this paper, a new generalization of the Cauchy distribution is proposed, namely, the exponentiated-exponential Cauchy distribution (EECD).

The Cauchy Distribution in Information Theory [PDF]

open access: yesEntropy, 2023
The Gaussian law reigns supreme in the information theory of analog random variables. This paper showcases a number of information theoretic results which find elegant counterparts for Cauchy distributions.

The Beta-Half-Cauchy Distribution [PDF]

open access: yesJournal of Probability and Statistics, 2011
On the basis of the half-Cauchy distribution, we propose the called beta-half-Cauchy distribution for modeling lifetime data. Various explicit expressions for its moments, generating and quantile functions, mean deviations, and density function of the ...

Index distribution of Cauchy random matrices [PDF]

open access: greenJournal of Physics A: Mathematical and Theoretical, 2014
Using a Coulomb gas technique, we compute analytically the probability $\mathcal{P}_ ^{(C)}(N_+,N)$ that a large $N\times N$ Cauchy random matrix has $N_+$ positive eigenvalues, where $N_+$ is called the index of the ensemble. We show that this probability scales for large $N$ as $\mathcal{P}_ ^{(C)}(N_+,N)\approx \exp\left[- N^2 _C(N_+/N)\right]$,

Multi-Scale Image Defogging Network Based on Cauchy Inverse Cumulative Function Hybrid Distribution Deformation Convolution [PDF]

open access: yesSensors
The aim of this study was to address the issue of significant performance degradation in existing defogging algorithms under extreme fog conditions. Traditional Taylor series-based deformable convolutions are limited by local approximation errors, while ...

Optimum Multilevel Thresholding for Medical Brain Images Based on Tsallis Entropy, Incorporating Bayesian Estimation and the Cauchy Distribution [PDF]

open access: goldApplied Sciences
Entropy-based thresholding is a widely used technique for medical image segmentation. Its principle is to determine the optimal threshold by maximizing or minimizing the image’s entropy, dividing the image into different regions or categories.

Statistical Inference of Truncated Cauchy Power-Inverted Topp–Leone Distribution under Hybrid Censored Scheme with Applications [PDF]

open access: goldAxioms, 2023
In this article, a new two-parameter model called the truncated Cauchy power-inverted Topp–Leone (TCP-ITL) is constructed by merging the truncated Cauchy power -G (TCP-G) family with the inverted Topp–Leone (ITL) distribution.

Cauchy or not Cauchy? New goodness-of-fit tests for the Cauchy distribution [PDF]

open access: greenStatistical Papers, 2021
AbstractWe introduce a new characterization of the Cauchy distribution and propose a class of goodness-of-fit tests for the Cauchy family. The limit distribution is derived in a Hilbert space framework under the null hypothesis. The new tests are consistent against a large class of alternatives. A comparative Monte Carlo simulation study shows that the

Cauchy-Distributed Functions and a Characterization of the Cauchy Distribution [PDF]

open access: diamondThe Annals of Mathematical Statistics, 1969
A simple representation of a class of functions of Cauchy variates whose members are also Cauchy variates is given. This leads to a characterization of the Cauchy distribution.
