In this paper, we extend the change point test for tail index proposed by Quintos, Fan, and Phillips (2001) to that based on autoregressive residuals. It is shown that the asymptotic null distribution of the test remains the same as that of the version in i.i.d. samples. A simulation study is carried out for illustration.
