Xiao Li

AI总结:

本研究提出一类经验贝叶斯预测分布,用于独立泊松观测量,在K-L损失下优于Jeffreys先验贝叶斯预测,且风险小于极小极大下界的1.04倍。

摘要:

本研究考虑了独立泊松观测量的同时预测分布,并使用Kullback-Leibler(K-L)损失评估预测分布的性能。本研究提出了一类经验贝叶斯预测分布,其优于基于Jeffreys先验的贝叶斯预测分布。经验贝叶斯预测分布的K-L风险被证明小于极小极大下界的1.04倍。

英文摘要:

In this study, simultaneous predictive distributions for independent Poisson observables were considered and the performance of predictive distributions was evaluated using the Kullback-Leibler (K-L) loss. This study proposes a class of empirical Bayesian predictive distributions that dominate the Bayesian predictive distribution based on the Jeffreys prior. The K-L risk of the empirical Bayesian predictive distributions is demonstrated to be less than 1.04 times the minimax lower bound.
