Characterization and Estimation of Double Weighted Rayleigh Distribution
Afaq Ahmad, S.P Ahmad, A. Ahmed

Abstract
This paper presents a new weighted distribution which is known as the Double Weighted Rayleigh Distribution (DWRD). This distribution is constructed and studied. The statistical properties of this distribution are discussed and obtained, including the mean, variance, coefficient of variation, harmonic mean, moments, mode, reliability function, hazard function and the reverse hazard function. Also the parameters of this distribution are estimated by the method of moment and the maximum likelihood estimation method.
