非负数据的Amoroso核密度估计(Igarashi和Kakizawa)是无边界偏置的,并且具有O(n− 4/5)阶的平均积分平方误差(MISE),其中是样本量。本文构造了Amoroso核密度估计及其导数关于光滑参数的线性组合。此外,我们提出了一个相关的乘法估计。我们证明了,如果底层密度是四次连续可微的,这些偏差减少估计的MISE达到收敛率n-8/9。我们说明了有限样本性能的估计,通过模拟。
The Amoroso kernel density estimator (Igarashi and Kakizawa ) for non-negative data is boundary-bias-free and has the mean integrated squared error (MISE) of orderO(n− 4/5), wherenis the sample size. In this paper, we construct a linear combination of the Amoroso kernel density estimator and its derivative with respect to the smoothing parameter. Also, we propose a related multiplicative estimator. We show that the MISEs of these bias-reduced estimators achieve the convergence ratesn− 8/9, if the underlying density is four times continuously differentiable. We illustrate the finite sample performance of the proposed estimators, through the simulations.
