Reliability Estimation for Lindley Distribution under Type-I Progressive Hybrid Censoring Scheme

Vaishali Gupta, Jitendra Kumar, M. S. Panwar, Sanjeev K Tomer


In this article we consider Lindley’s distribution as a lifetime model and provide procedures to evaluate reliability measures in the presence of Type-I progressively hybrid censored data. We obtain maximum likelihood and Bayes estimators of parameter, reliability function, hazard rate function and mean time to system failure. We also provide confidence intervals and Bayesian credible intervals for parameter of considered distribution. Finally, we perform simulation study for numerical illustrations.
