Recently, a novel improved adaptive Type-II progressive censoring strategy has been suggested in order to obtain adequate data from trials that require a lengthy amount of time. Considering this scheme, this paper focuses on various classical and Bayesian estimation challenges for parameter and some reliability metrics for the XLindley distribution. Two classical estimation methods are considered from the classical perspective to get the point and interval estimations of the model parameter as well as reliability and hazard rate functions. In addition to the usual approaches, the Bayesian methodology is looked at by leveraging the squared error loss function and the Markov chain Monte Carlo technique. The Bayes point and credible intervals are obtained based on two forms of the posterior distribution. A simulation examination is implemented adopting multiple circumstances to distinguish between the conventional and Bayesian estimations. The simulation results demonstrate that the Bayesian approach using the likelihood function is superior for estimating the model parameter when compared with the other methods. In contrast, when estimating reliability metrics, it is advisable to utilize the Bayesian method with the spacings function. Two real-world data sets are analyzed to integrate the proposed approaches into practice, and the ideal progressive censoring strategy is chosen using some optimality criteria.
最近,为了从需要很长时间的试验中获取足够的数据,人们提出了一种新颖的改进型自适应II型渐进删失策略。考虑到该方案,本文聚焦于XLindley分布的参数以及一些可靠性指标的各种经典和贝叶斯估计挑战。从经典角度考虑了两种经典估计方法,以获得模型参数以及可靠性和失效率函数的点估计和区间估计。除了常用方法外,还通过利用平方误差损失函数和马尔可夫链蒙特卡罗技术来研究贝叶斯方法。基于两种后验分布形式获得贝叶斯点估计和可信区间。采用多种情况进行模拟检验,以区分传统估计和贝叶斯估计。模拟结果表明,与其他方法相比,使用似然函数的贝叶斯方法在估计模型参数方面更具优势。相比之下,在估计可靠性指标时,建议使用具有间距函数的贝叶斯方法。分析了两个实际数据集,将所提出的方法应用于实践,并使用一些最优性标准选择理想的渐进删失策略。
