On some properties of Rayleigh-Cauchy distribution

, 2021
We introduce a three-parameter univariate continuous distribution called the Raleigh-Cauchy Distribution (RCD) to extend the two-parameter Cauchy distribution using T-R{Y} families.

Generalized cauchy distributions [PDF]

Annals of the Institute of Statistical Mathematics, 1957
Statistical distributions of the form C(l + [' x | )~ are considered. For k = 2, m = 1 this is the Cauchy distribution. For k = 2, m == ^(n -\1), % == n~&, it is the Student-Fisher distribution with n degrees of freedom. The Cauchy distribution is of interest because the variance of the mean is infinite while that of the median is finite. In this paper

A truncated Cauchy distribution

International Journal of Mathematical Education in Science and Technology, 2006
A truncated version of the Cauchy distribution is introduced. Unlike the Cauchy distribution, this possesses finite moments of all orders and could therefore be a better model for certain practical situations. One such situation in finance is discussed. Explicit expressions for the moments of the truncated distribution are also derived.

On the modified skew-normal-Cauchy distribution: properties, inference and applications

, 2020
In this paper, we study further properties of the modified skew-normal-Cauchy (MSNC) distribution. MSNC distribution corresponds to a reformulation of skew-normal-Cauchy distribution that allows to obtain a nonsingular Fisher Information Matrix at ...

Distributive Cauchy lattices

Algebra Universalis, 1984
The author has pioneered the study of completions of lattice ordered groups by means of Cauchy structures. This paper extends this study to arbitrary distributive lattices by means of Cauchy structures obtained from two intrinsic (and generally non-topological) lattice convergences called \(\alpha\) and \(\beta\).

Bias prevention of maximum likelihood estimates for skew-normal-Cauchy distribution

Communications in statistics. Simulation and computation, 2018
This work focuses on the so-called skew-normal-Cauchy distribution, which is a convenient alternative to the skew-normal distribution for modeling data in presence of asymmetries. A stochastic representation and further nice properties of the skew-normal-
