Topp-Leone generalized Rayleigh distribution and its applications [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2018
A new three-parameter lifetime distribution called the Topp-Leone generalized Rayleigh (TLGR) distribution obtained by the Topp-Leone generator based on the generalized Rayleigh (GR) distribution is proposed.

stochastic model for generalized Rayleigh distribution using three sources

International journal of health sciences, 2022
Of all Cancers, Oral cancer is one of the most typical cancers in the world. Oral cancer has delayed clinical detection, poor prognosis, without specific biomarkers, and expensive therapeutic methods. This study aims to explain the basic aspects of oral cancers and focuses on squamous cell carcinoma of the oral cavity.

STATISTICAL INFERENCE FOR GEOMETRIC PROCESS WITH THE GENERALIZED RAYLEIGH DISTRIBUTION [PDF]

Facta Universitatis, Series: Mathematics and Informatics, 2021
In the present paper, statistical inference problem is considered for the geometric process (GP) by assuming the distribution of the first arrival time is generalized Rayleigh with the parameters $\alpha$ and $\lambda$. We use the maximum likelihood method for obtaining the ratio parameter of the GP and distributional parameters of the generalized ...

Moments of generalized order statistics for Pareto-Rayleigh distribution

Open Journal of Mathematical Sciences, 2021
In this paper, we derive the explicit expressions for single and product moments of generalized order statistics from Pareto-Rayleigh distribution using hypergeometric functions. Also, some interesting remarks are presented.

Evaluating the Discrete Generalized Rayleigh Distribution: Statistical Inferences and Applications to Real Data Analysis [PDF]

Mathematics
Various discrete lifetime distributions have been observed in real data analysis. Numerous discrete models have been derived from a continuous distribution using the survival discretization method, owing to its simplicity and appealing formulation.

Relations for Moments of Dual Generalized Order Statistics from Exponentiated Rayleigh Distribution and Associated Inference [PDF]

Journal of Statistical Theory and Applications (JSTA), 2019
In this paper we obtain exact expressions and some recurrence relations satisfied by single and product moments of dual generalized order statistics from exponentiated Rayleigh distribution. These relations are deduced for moments of order statistics and
