Estimation of stress-strength reliability using record ranked set sampling scheme from the exponential distribution

Jafar Ahmadi


‎In this paper‎, ‎point and interval estimation of stress-strength reliability based on upper  record ranked set sampling (RRSS) from one-parameter exponential distribution are considered‎. ‎Maximum likelihood estimator (MLE) as well as the uniformly minimum variance unbiased estimator (UMVUE) of stress-strength parameter are derived and their performance are studied‎. ‎Also‎, ‎some confidence intervals for stress-strength reliability based on upper  RRSS  are constructed and then compared on the basis of a simulation study‎. ‎Finally‎, ‎a data set has been analyzed for illustrative purposes‎.
