Abstract

This study develops a Bayesian approach for estimating the unknown parameters of the 3-component mixture of geometric (3-CMG) model under a doubly type-I censoring scheme (DT1CS). The derivations of the Bayes estimators (BEs) and Bayes risks (BRs) are presented under square error loss function (SELF), precautionary loss function (PLF) and DeGroot loss function (DLF) using Beta prior under DT1CS. The strategy is evaluated through extensive simulation and real-life data analysis, showing the strength and efficiency of the newly proposed model. The study recommends that the SELF is the optimal choice for accurately estimating the unknown parameters of the 3-CMG model.

双 1 型普查方案下多成分几何寿命测试模型的贝叶斯估计策略

本研究开发了一种贝叶斯方法，用于估计双 I 型普查方案（DT1CS）下三分量混合几何模型（3-CMG）的未知参数。在 DT1CS 下使用 Beta 先验的平方误差损失函数（SELF）、预防性损失函数（PLF）和 DeGroot 损失函数（DLF）下，介绍了贝叶斯估计器（BEs）和贝叶斯风险（BRs）的推导。通过大量的模拟和实际数据分析，对该策略进行了评估，显示了新提出模型的优势和效率。研究建议 SELF 是准确估计 3-CMG 模型未知参数的最佳选择。
