摘要

本文研究了在贝叶斯和极大似然框架下对数分布尺度参数的估计问题。后验分析假设了均匀和杰弗里斯先验。给出了五种不同损失函数下的贝叶斯估计量和相关风险。在每个先验条件下构造了可信区间和最高后验密度区间。为了说明结果的数值应用,并比较不同估计器的性能,进行了仿真研究。目的是比较基于贝叶斯和最大似然框架的估计器的性能。用五种不同的损失函数比较了不同贝叶斯估计器的性能。研究表明,对于上述参数的估计,贝叶斯估计优于极大似然估计。而对于贝叶斯估计,则可以有效地利用Jeffreys下的熵损失函数。

A Note on Bayesian and Maximum Likelihood Estimation of Scale Parameter of Log Gamma Distribution
In this paper, the prob lem o f estimating the scale parameter of log gamma distribution under Bayesian and maximu m likelihood framework has been addressed. The uniform and Jeffreys priors have been assumed for posterior analysis. The Bayes estimators and associated risks have been derived under five different loss functions. The credible intervals and highest posterior density intervals have been constructed under each prior. A simulat ion study has been carried out to illustrate the numerical applicat ions of the results and to compare the performance of different estimators. The purpose is to compare the performance of the estimators based on Bayesian and maximu m likelihood framewo rks. The performance of different Bayes estimators has also been compared using five d ifferent loss functions. The study indicated that for estimation of the said parameter, the Bayesian estimation can be preferred over maximu m likelihood estimation. While in case of the Bayesian estimation, the entropy loss function under Jeffreys can effectively be emp loyed.
