摘要：

This paper considers the problem of testing parameter constancy in GARCH(1,1) models. A cusum of squares test is proposed in analogy of Inclan and Tiao (1994)'s statistic. Its limiting distribution is derived via using the invariance principle for mixingale sequences obtained by McLeish (1975). Simulation results are illustrated to demonstrate the validity of the cusum test.
