Öğe COMPARISON OF ESTIMATORS FOR STRESS-STRENGTH RELIABILITY IN THE GOMPERTZ CASE(HACETTEPE UNIV, FAC SCI, 2009) Saracoğlu, Buğra; Kaya, Mehmet Fedai; Abd-Elfattah, Abdallah MahmoudIn this paper, the Bayesian and non Bayesian estimation problem of reliability, R = P(Y < X), will be considered when X and Y are two independent but not identically random variables belonging to the Gompertz distribution. The three estimation methods applied were the maximum likelihood, uniformly minimum variance unbiased, and Bayes estimators. A numerical illustration is used to compare the three different estimators.Öğe Estimating system reliability of competing weibull failures with censored sampling(Selcuk University Research Center of Applied Mathematics, 2009) Abd-Elfattah, Abdallah Mahmoud; Mohamed, Marwa O.In this paper, we consider the estimation of R=P(Y
