This chapter considers the limiting behavior of the well-known CUSUM SQ test for suitably defined sequences of local alternatives describing heteroscedasticity. It is shown that under certain circumstances the asymptotic behavior of the CUSUM-SQ test can be computed even for alternatives describing changes of the conditional variance of the error term (e.g., ARCH-processes).
