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.

The skew-Cauchy distribution

Statistics & Probability Letters, 2000
Abstract Suppose ( X ,Y) has a ( k +1)-dimensional Cauchy distribution. Consider the conditional distribution of X given Y > y 0 , for some fixed value of y 0 ∈ R . The resulting distribution is the multivariate skewed Cauchy, in which there is truncation with respect to Y : this is but one of a general class of skewed ...

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 ...

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.

Generalized cauchy distributions [PDF]

open access: possibleAnnals 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
