摘要
统计预测分析在广泛的领域中发挥着重要的作用。例子包括工程系统、实验设计等。本文基于渐进式ⅱ型右截尾数据,分别在信息先验和非信息先验条件下,建立了贝叶斯双样本点和区间预测模型。通过假设一个广义指数模型,对任意渐进删减方案的未来渐进式ii型删减样本,在平方误差损失(SEL)和线性指数损失(LINEX)函数下得到阶统计量的预测界和贝叶斯点预测量。所得结果可用于寿命试验中试验总时间的预测。除了数值方法外,Gibbs抽样过程(如Markov Chain Monte Carlo方法)用于评估SEL和LINEX损失函数下的近似预测界和Bayes点预测量。对于每种方法,所提出的预测程序的性能也通过蒙特卡罗模拟研究和说明性示例进行了验证。
Bayesian Two-sample Prediction with Progressively Censored Data for Generalized Exponential Distribution Under Symmetric and Asymmetric Loss Functions
Statistical prediction analysis plays an important role in a wide range of fields. Examples include engineering systems, design of experiments, etc. In this paper, based on progressively Type-II right censored data, Bayesian two-sample point and interval predictors are developed under both informative and non-informative priors. By assuming a generalized exponential model, prediction bounds as well as Bayes point predictors are obtained under the squared error loss (SEL) and the Linear-Exponential (LINEX) loss functions for the order statistic in a future progressively Type-II censored sample with an arbitrary progressive censoring scheme. The derived results may be used for prediction of total time on test in lifetime experiments. In addition to numerical method, Gibbs sampling procedure (as Markov Chain Monte Carlo method) are used to assess approximate prediction bounds and Bayes point predictors under the SEL and LINEX loss functions. The performance of the proposed prediction procedures are also demonstrated via a Monte Carlo simulation study and an illustrative example, for each method.
