时间序列模型的变点检验与NED序列的极限定理

Testing for change points in time series models and limiting theorems for NED sequences

Shiqing Ling

摘要:

本文首先建立了近历元相关序列前后向和的强大数律和强不变原理。利用这些极限定理,我们发展了一个一般的渐近理论的Wald测试的变点在一般类的时间序列模型下的无变点假设。作为一个应用,我们验证了我们的假设的长记忆分数ARIMA模型。

英文摘要:

This paper first establishes a strong law of large numbers and a strong invariance principle for forward and backward sums of near-epoch dependent sequences. Using these limiting theorems, we develop a general asymptotic theory on the Wald test for change points in a general class of time series models under the no change-point hypothesis. As an application, we verify our assumptions for the long-memory fractional ARIMA model.
