本文导出了时间序列回归模型$z_t=f(X_t)+w_t$的非参数估计的渐近理论,其中,nsuremath{X_t}和nsuremath{z_t}是可观测的非平稳过程,w_t}$是不可观测的平稳过程。在计量经济学中,这可以解释为一种非线性协整关系,但我们相信我们的结果具有更广泛的意义。$\{x_t\}$允许的非平稳过程类是空递归马尔可夫链类的子类。这个子类包含随机游动,单位根过程和非线性过程。在f(x)为满足混合条件的马氏链的假设下,我们得到了f(x)的非参数估计的渐近性。通过模拟实验研究了$\hat{f}(x)$的有限样本性质。

英文摘要:
We derive an asymptotic theory of nonparametric estimation for a time series regression model $Z_t=f(X_t)+W_t$, where \ensuremath\{X_t\} and \ensuremath\{Z_t\} are observed nonstationary processes and $\{W_t\}$ is an unobserved stationary process. In econometrics, this can be interpreted as a nonlinear cointegration type relationship, but we believe that our results are of wider interest. The class of nonstationary processes allowed for $\{X_t\}$ is a subclass of the class of null recurrent Markov chains. This subclass contains random walk, unit root processes and nonlinear processes. We derive the asymptotics of a nonparametric estimate of f(x) under the assumption that $\{W_t\}$ is a Markov chain satisfying some mixing conditions. The finite-sample properties of $\hat{f}(x)$ are studied by means of simulation experiments.
