Efficiency of ranked set sampling designs in power Lindley system reliability estimation with uncensored and right-censored data by Zhimin Wu, Lin Xiang

“…To obtain the parameter estimates of the PL distributions, the maximum likelihood (ML) method is used. Monte Carlo simulations considering perfect and imperfect ranking with uncensored data and perfect ranking with right-censored data show that RSS and ERSS provide more precise ML estimates of system reliability, R, compared to SRS under different sample sizes and parameter settings. …”
