Abstract In this paper, we define the adaptive Weighted Nadaraya–Watson estimation (AWNW) of the conditional distribution function (cdf) for independent and identically distributed (iid) data using varying bandwidth. The asymptotic normality of the proposed estimator is investigated. The results of the simulation studies show that the proposed estimation have better performance than the Weighted Nadaraya–Watson estimation with fixed bandwidth.

通过改变带宽对条件分位数进行自适应加权 Nadaraya-Watson 估计

摘要 在本文中,我们为使用不同带宽的独立和同分布 (iid) 数据定义了条件分布函数 (cdf) 的自适应加权 Nadaraya-Watson 估计 (AWNW)。研究了所提出的估计量的渐近正态性。仿真研究的结果表明,所提出的估计比具有固定带宽的加权 Nadaraya-Watson 估计具有更好的性能。
