Statistical inference in Burr type XII lifetime model based on progressive randomly censored data

AbstractCensoring commonly occurs in real-world scenarios, either intentionally or unintentionally. Unintentional (or accidental) censoring usually happens randomly, i.e., it is out of the experimenters’ control, such as broken equipment, lack of follow-up, etc. Experimenters typically use intentional censoring to save experimental time and cost. In this article, we develop frequentist and Bayesian statistical inferential procedures for the parameters and reliability characteristics of the Burr type XII lifetime model under the Koziol-Green model based on progressive randomly censored data. For the frequentist approach, maximum likelihood methods for point and interval estimation are developed. For the Bayesian approach, the Bayes estimates under the squared error loss function (SELF) are evaluated using the Markov Chain Monte Carlo (MCMC) and Tierney-Kadane (T-K) approximation techniques. A Monte Carlo simulation study is used to assess the performance of the proposed estimation procedures. A real data analysis is performed to illustrate the proposed methods. Moreover, obtaining progressive censoring schemes for experimental planning purposes is also discussed.Keywords: Bayesian estimationKoziol-Green modelMarkov chain Monte Carlo methodmaximum likelihood estimationprogressively Type-II censoring AcknowledgementsThe authors would like to thank the guest editor and two anonymous reviewers for their positive remarks and useful comments.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationNotes on contributorsRajni GoelDr. Rajni Goel is an assistant professor in the Department of Mathematics, Chandigarh University, Mohali, Punjab, India.
