密度估计中的置信带

Confidence bands in density estimation

Evarist Giné, Richard Nickl

摘要:

给定一个未知连续密度$f:\mathbb{R}\to\mathbb{R}$的样本,我们构造自适应置信带,该置信带对$t$ -Hölder球联合的“通用”子集$0<t\le r$中的所有密度都是诚实的,其中$r$是一个固定但任意的整数。我们的结果不成立的例外(“非一般”)密度集在相关的Hölder范数拓扑中是无处稠密的。在证明过程中,我们还得到了线性小波和核密度估计的极大值的极限定理,这是独立的兴趣。

英文摘要:

Given a sample from some unknown continuous density $f:\mathbb{R}\to\mathbb{R}$, we construct adaptive confidence bands that are honest for all densities in a "generic" subset of the union of $t$-Hölder balls, $0<t\le r$, where $r$ is a fixed but arbitrary integer. The exceptional ("nongeneric") set of densities for which our results do not hold is shown to be nowhere dense in the relevant Hölder-norm topologies. In the course of the proofs we also obtain limit theorems for maxima of linear wavelet and kernel density estimators, which are of independent interest.
