基于抽样连续过程的趋势的非参数估计

Nonparametric estimation of a trend based upon sampled continuous processes

David Degras

摘要:

设X是以紧区间[0,T]为指标的二阶随机过程.假设在p个时间点的固定网格上观察到X的n个独立实现。在X的样本路径上的弱正则性假设下,证明了当n,p趋于无穷大时,在C([0,T])空间中趋势函数mu = EX的合适的非参数估计的渐近正态性,并利用高斯过程理论,得到了mu的近似同时置信带.

英文摘要:

Let X be a second order random process indexed by a compact interval [0,T]. Assume that n independent realizations of X are observed on a fixed grid of p time points. Under mild regularity assumptions on the sample paths of X, we show the asymptotic normality of suitable nonparametric estimators of the trend function mu = EX in the space C([0,T]) as n, p go to infinity and, using Gaussian process theory, we derive approximate simultaneous confidence bands for mu.
