摘要
设f_n是基于一个核函数K和取值于R~d的独立同分布随机变量列的一个非参数核密度估计.本文证明了{f_n(x)-f_n(-x),n≥1}在L_1(R~d)空间下的两个中偏差定理.
Let f_n be a non-parametric kernel density estimator based on a kernel function K and a sequence of independent and identically distributed random variables taking values in R~d. In this paper we prove two moderate deviation theorems in L_1(R~d) for {f_n(x)-f_n(x), n≥1}.
