Pólya和核与Bayes估计

The Pólya sum kernel and Bayes estimation

Mathias Rafler

摘要:

我们认为一个特定的Cox过程从贝叶斯的观点和贝叶斯估计的强度措施是所谓的Pólya和内核,最近发生的背景下,建设的所谓的Papangelou过程。更准确地说,如果先验,考克斯过程的直接测度,是泊松-伽马随机测度,那么后验也是泊松-伽马随机测度,强度的贝叶斯估计是波利亚和核。此外,我们将这一结果扩展到双随机Poisson-Gamma先验,并给出了条件下,人们可以确定的贝叶斯估计的强度。

英文摘要:

We consider a particular Cox process from a Bayesian viewpoint and show that the Bayes estimator of the intensity measure is the so-called Pólya sum kernel, which occurred recently in the context of the construction of the so-called Papangelou processes. More precisely, if the prior, the directing measure of the Cox process, is a Poisson-Gamma random measure, then the posterior is again a Poisson-Gamma random measure and the Bayes estimator of the intensity is the Pólya sum kernel. Moreover, we extend this result to doubly stochastic Poisson-Gamma priors and give conditions under which one can identify the Bayes estimator for the intensity.
