The reliability of a component depends on the stress conditions operating environment, which are uncertainty and should be modeled as random. This article deals with estimation stress-strength parameter Weibull-Rayleigh distribution. Let X Y two independent random variables, where follow maximum likelihood estimator approximate obtained. Other properties distributions derived. Two real data app...

Many lifetime distribution models have successfully served as population for risk analysis and reliability mechanisms. We propose a novel estimation procedure of stress–strength in the case two independent unit-half-normal distributions can fit asymmetrical data with either positive or negative skew, different shape parameters. obtain maximum likelihood estimator reliability, its asymptotic dis...
