In this paper, the inference of multicomponent stress-strength reliability has been derived using progressively censored samples from Topp-Leone distribution. Both stress and strength variables are assumed to follow Topp-Leone distributions with different shape parameters. The maximum likelihood estimate along with the asymptotic confidence interval are developed. Boot-p and Boot-t confidence intervals are also constructed. The Bayes estimates under generalized entropy loss function based on gamma priors using Lindley's, Tierney-Kadane's approximation and Markov chain Monte Carlo methods are derived. A simulation study is considered to check the performance of various estimation methods and different censoring schemes. A real data study shows the applicability of the proposed estimation methods.
在本文中,利用来自Topp-Leone分布的逐步删失样本推导了多分量应力-强度可靠性的推断。假设应力和强度变量均服从具有不同形状参数的Topp-Leone分布。推导了最大似然估计及其渐近置信区间。还构建了Boot-p和Boot-t置信区间。基于伽马先验,使用林德利近似法、蒂尔尼-卡丹近似法和马尔可夫链蒙特卡罗方法,推导了广义熵损失函数下的贝叶斯估计。进行了一项模拟研究,以检验各种估计方法和不同删失方案的性能。一项实际数据研究表明了所提出估计方法的适用性。
