密度估计的Bagging

Bagging of Density Estimators

Mathias Bourel, Jairo Cugliari

摘要:

在这项工作中,我们给出了新的密度估计平均经典的密度估计,如直方图,频率多边形和核密度估计在不同的自助样本的原始数据。我们证明了这些新的估计的L2-一致性,并通过大量的模拟比较它们与几种类似的方法。在此基础上,给出了目标密度的非参数逐点置信区间的构造方法。

英文摘要:

In this work we give new density estimators by averaging classical density estimators such as the histogram, the frequency polygon and the kernel density estimators obtained over different bootstrap samples of the original data. We prove the L 2-consistency of these new estimators and compare them to several similar approaches by extensive simulations. Based on them, we give also a way to construct non parametric pointwise confidence intervals for the target density.
