  • 所以,非單一線性模型在近年來已經被廣泛的討論.臨界自迴歸模型(threshold autoregression model)用以描述非單一模型的時間數列資料,在非線性的時間序列資料的應用十分廣泛.本文主要依據Chan (1990)單變量臨界自迴歸模型的檢定方法,與Chan (1991)中求取檢定統計量漸近分配之方法,推廣至多變量模型,並驗證近似分配之準確度.
    Tsay(1989)及Tsay(1998)對於單變量與多變量臨界自迴歸模型提出一個檢定方法,並且做模擬來檢定其統計量的檢定力近似分配,本文將會在與Tsay相同模擬情況下,檢定Chan之統計量的檢定力,並就兩者之檢定力比較之.
