摘要: 研究了条件泛函及其导数的非参数估计,对随机与固定设计的条件泛函,分别利用核估计和非参数加权估计,在核函数及权函数满足一定条件下,证明了估计一致强收敛于待估函数的速度可达到最优.从而进一步推广和发展了Härdle,etal.(1988)、Severini,etal.(1992)的许多结果.

Abstract: In this paper, the nonparameteric estimations of conditional functional and its derivatives are studied. Strong uniform convergence rates are proved to be optimal for kernel type estimator and weighted estimator of conditional functional in the random design and the fixed design,under certain conditions. Various previous results in the literature (for example Härdle etal. (1988).Severini and Wong (1992) are extended and sharpened.
