摘要
本文假设产品寿命服从两参数 Weibull分布 ,在定数截尾寿命试验的情况下 ,利用近年来发展起来的 Gibbs抽样算法 ,设计了计算参数贝叶斯估计的 Gibbs抽样方案 ,计算了一个实例并与经典的 BL UE和 BL IE估计结果进行比较。结果表明 ,较之传统的数值积分法 ,Gibbs抽样算法使用起来方便直接 。
To make the bayesian inference for life-testing problems involving Weibull Disfribution,an approach based on Gibbs Sampler is proposed in this paper.One empirical example illustrates the Ueility of the approach,and the estimation results are compared with the traditional BLUE and BLIE.it is shown that using this approach to evaluate the Bayesian estimates is more comvenient and straightforward than the numerical integration method.
