Slashed generalized Rayleigh distribution

Communications in Statistics - Theory and Methods, 2016
ABSTRACTWe introduce a new family of distributions suitable for fitting positive data sets with high kurtosis which is called the Slashed Generalized Rayleigh Distribution. This distribution arises as the quotient of two independent random variables, one being a generalized Rayleigh distribution in the numerator and the other a power of the uniform ...

Modelling SAR images with a generalisation of the Rayleigh distribution

Conference Record of the Thirty-Fourth Asilomar Conference on Signals, Systems and Computers (Cat. No.00CH37154), 2002
Synthetic aperture radar (SAR) imagery has found important applications due to its clear advantages over optical satellite imagery one of them being able to operate in various weather conditions. However, due to the physics of the radar imaging process, SAR images contain unwanted artifacts in the form of a granular look which is called speckle.

CHARACTERIZATIONS THROUGH THE GENERALIZED INVERTED RAYLEIGH DISTRIBUTION

Far East Journal of Theoretical Statistics, 2016
Summary: In this article, the generalized inverted Rayleigh distribution (GIRD) is presented and some of the statistical properties of this distribution are obtained. First, we studied the shape of hazard function. Next, we derived the quantile function, median, mode, moments, harmonic mean, skewness and kurtosis.

Discriminating between the generalized Rayleigh and Weibull distributions

Journal of Applied Statistics, 2013
Generalized Rayleigh (GR) and Weibull (WE) distributions are used quite effectively for analysing skewed lifetime data. In this paper, we consider the problem of selecting either GR or WE distribution as a more appropriate fitting model for a given data set.

Transmuted Generalized Rayleigh Distribution

Journal of Statistics Applications & Probability, 2014
In this article, we generalize the generalized Rayleigh distribution using the qu adratic rank transmutation map studied by Shaw et al. (9) to develop a transmuted generalized Rayleigh distribution. We provide a comprehensive description of the mathematical properties of the subject distribution along with its reliability behav ior.

A generalized Gompertz-Rayleigh model as a survival distribution

Mathematical Biosciences, 1984
Abstract A generalized Gompertz-Rayleigh distribution is proposed as a potential survival distribution for the case of modeling dual components of risk acting on a population. The hazard function is expressed as the sum of two risks. The early risk component allows for either a high initial death rate that can decrease rapidly or an initial death ...

Estimate of Distribution for SAR Image Based on the Generalized Rayleigh Distribution

2006 6th World Congress on Intelligent Control and Automation, 2006
Generalized Rayleigh distribution was deduced for the amplitude SAR image according to the generalized central limit theorem, and the parameters were estimated by the negative order moment. Based on the disadvantage of single-point estimation, global search was suggested to achieve the optimal parameters.
