空间齐次Poisson点过程强度的Stein估计

Stein estimation of the intensity of a spatial homogeneous Poisson point process

Marianne Clausel, Jean-François Coeurjolly, Jérôme Lelong

摘要:

在本文中,我们重温了Stein的原始思想,并提出了一个估计的齐次泊松点过程定义在$\R^d$的强度参数,并在一个有界的窗口中观察。该程序是基于一个新的一般分部积分法公式的泊松点过程。我们表明,我们的斯坦估计优于最大似然估计的均方误差。特别是,我们表明,在许多实际情况下,我们有一个大于30%的增益。

英文摘要:

In this paper, we revisit the original ideas of Stein and propose an estimator of the intensity parameter of a homogeneous Poisson point process defined in $\R^d$ and observed in a bounded window. The procedure is based on a new general integration by parts formula for Poisson point processes. We show that our Stein estimator outperforms the maximum likelihood estimator in terms of mean squared error. In particular, we show that in many practical situations we have a gain larger than 30\%.
