A new versatile modification of the Rayleigh distribution for modeling COVID-19 mortality rates [PDF]

Results in Physics, 2022
The aim of this paper is to specify a new flexible statistical model to analyze COVID-19 mortality rates in Italy and Canada. A new versatile lifetime distribution with four parameters is proposed by using the exponentiated generalized class of ...

Inverse Lomax-Rayleigh distribution with application [PDF]

Heliyon, 2021
In this paper, an extension of Rayleigh distribution called Inverse Lomax Rayleigh (ILR) is proposed by using the Inverse Lomax generator of [13]. Properties of ILR were derived. This includes the complete and incomplete moments, entropy, distribution of

Slashed Rayleigh Distribution

Revista Colombiana de Estadística, 2015
In this article we study a subfamily of the slashed-Weibull family. This subfamily can be seen as an extension of the Rayleigh distribution with more flexibility in terms of the kurtosis of distribution.

Transmuted Rayleigh Distribution

Austrian Journal of Statistics, 2016
In this article, we generalize the Rayleigh distribution using the quadratic rank transmutation map studied by Shaw et al. (2009) to develop a transmuted Rayleigh distribution.

Slashed Exponentiated Rayleigh Distribution

Revista Colombiana de Estadística, 2015
In this paper we introduce a new distribution for modeling positive data with high kurtosis. This distribution can be seen as an extension of the exponentiated Rayleigh distribution.

Classical and Bayesian Inference for the Two-Parameter Rayleigh Distribution with Random Censored Data [PDF]

Entropy
This study focuses on parameter estimation and reliability analysis for the two-parameter Rayleigh distribution under random censoring. It is shown that directly fitting the standard Rayleigh distribution can lead to substantial estimation errors ...

Half logistic exponentiated inverse Rayleigh distribution: Properties and application to life time data. [PDF]

PLoS ONE
This paper presents a novel extension of the exponentiated inverse Rayleigh distribution called the half-logistic exponentiated inverse Rayleigh distribution. This extension improves the flexibility of the distribution for modeling lifetime data for both
