摘要 该文将Hrdle和Tsybakov的结果推广到数据来自α-混合的严平稳序列的情形,得到了估计的相合性和渐近正太性.在小样本的情形下给出了随机模拟结果,以检查所提出估计的表现. Hardle and Tsybakov's results([6,p120-135]) is extended to the case where samples are drawn from the strictly stationary sequence withα-mixing.The consistency and asymptotic normality of the estimators are obtained.Simulation studies are conducted to examine the small-sample properties of the proposed estimates.
