一类鞅的一致收敛性及其在非线性协整回归中的应用

Uniform convergence rates for a class of martingales with application in non-linear cointegrating regression

Qiying Wang, Nigel Chan

摘要:

对于一类鞅,本文给出了一个具有广泛适用性的一致相合性的框架。主要条件仅与鞅的条件方差有关,这对平稳混合时间序列、平稳迭代随机函数、Harris递归马尔可夫链和新息为线性过程的$I(1)$过程都成立.利用已有的结果,研究了非线性协整回归模型中Nadaraya-Watson估计的一致收敛性.我们的结果不仅提供了尖锐的收敛速度,但也保持一致收敛性的最佳范围。本文还考虑了Harris回归马尔可夫链的泛函的一致上、下界估计,它们是独立的.

英文摘要:

For a class of martingales, this paper provides a framework on the uniform consistency with broad applicability. The main condition imposed is only related to the conditional variance of the martingale, which holds true for stationary mixing time series, stationary iterated random function, Harris recurrent Markov chains and $I(1)$ processes with innovations being a linear process. Using the established results, this paper investigates the uniform convergence of the Nadaraya-Watson estimator in a non-linear cointegrating regression model. Our results not only provide sharp convergence rate, but also the optimal range for the uniform convergence to be held. This paper also considers the uniform upper and lower bound estimates for a functional of Harris recurrent Markov chain, which are of independent interests.
