摘要
本文给出了条件三阶中心矩的局部线性估计, 并研究了估计的条件偏差和方差. 本文利用广义交叉核实法(GCV)进行窗宽选择. 我们通过模拟说明了该估计的实用性.
In this paper,we propose a local linear estimator for conditional third central moment.The asymptotic bias and variance are derived.General cross validation(GCV) is recommended for bandwidth selection.A simple simulation study is carried out to illustrate the usefulness of the proposed method.
