Confidence disc and square for Cauchy distributions
Ukrains’kyi Matematychnyi Zhurnal, 2023 UDC 519.21 We construct a confidence region of parameters for a sample of size N from the Cauchy distributed random variables. Although Cauchy distribution has two parameters, a location parameter μ ∈ ℝ and a scale parameter σ > 0 , we infer them simultaneously by regarding them as a single complex parameter γ : = μ

Ratios and Cauchy Distribution
, 2016 It is well known that the ratio of two independent standard Gaussian random variables follows a Cauchy distribution. Any convex combination of independent standard Cauchy random variables also follows a Cauchy distribution. In a recent joint work, the author proved a surprising multivariate generalization of the above facts. Fix $m > 1$ and let $ $

The gamma half-Cauchy distribution: Properties and applications
, 2016 A new distribution, namely, the Gamma-Half-Cauchy distribution is Gamma-Half-Cauchy distribution proposed. Various properties of the are studied in detail such as limiting behavior, moments, mean devi- ations and Shannon entropy. The model parameters are

A method for generating distributions with an application to Cauchy distribution
Research in StatisticsThere are numerous transformation methods which are in use right now. In this article, the newly proposed model is achieved by using the transformation method known as beta transformation where it does not require more than one additional parameters to ...

Test of fit for Cauchy distribution based on the empirical likelihood ratio with application to the stock market price [PDF]
Journal of Mahani Mathematical Research, 2022 Recently, it has been shown that the density based empirical likelihood concept extends and standardizes these methods, presenting a powerful approach for approximating optimal parametric likelihood ratio test statistics.

Neutrosophic Stable Random Variables [PDF]
Neutrosophic Sets and Systems, 2022 In this paper, the concept of a neutrosophic stable random variable is introduced. Two definitions of a neutrosophic random variable are presented. We introduced both the neutrosophic probability distribution function and the neutrosophic probability ...

Characterizations of the Maximum Likelihood Estimator of the Cauchy Distribution [PDF]
Lobachevskii Journal of Mathematics, 2021 This paper gives a new approach for the maximum likelihood estimation of the joint of the location and scale of the Cauchy distribution. We regard the joint as a single complex parameter and derive a new form of the likelihood equation of a complex ...
