一般因果时间序列的强一致性模型选择

Strong consistent model selection for general causal time series

William Kengne

摘要:

本文研究了一类因果时间序列模型的强相容性问题,包括AR($\infty$),ARMA($\infty$),TMAMA($\infty$),ARMA-GMAMA以及许多经典的其它过程.我们提出了一个惩罚标准的基础上拟似然模型。我们提供了充分条件,确保强一致性的建议程序。所选模型参数的估计量也服从重对数重对数律。看来,与Bardet { \it et al.} \cite{Bardet2020},不需要正则化参数和模型结构之间的依赖性。

英文摘要:

We consider the strongly consistent question for model selection in a large class of causal time series models, including AR($\infty$), ARCH($\infty$), TARCH($\infty$), ARMA-GARCH and many classical others processes. We propose a penalized criterion based on the quasi likelihood of the model. We provide sufficient conditions that ensure the strong consistency of the proposed procedure. Also, the estimator of the parameter of the selected model obeys the law of iterated logarithm. It appears that, unlike the result of the weak consistency obtained by Bardet {\it et al.} \cite{Bardet2020}, a dependence between the regularization parameter and the model structure is not needed.
