- Chapter 6 presents the methods for online detection of a change in the unconditional volatility. A test based on a moving sum is proposed and evaluated. The test has a controlled asymptotic size, i.e. the false alarm probability during an infinitely long monitoring period is fixed. The effects of autoregression and conditional heteroscedasticity have been also addressed and a test that allows for heteroscedasticity has been proposed. The testing procedures are exemplified with the Hang Seng Index to see whether a shift during the Asian crises period could have been detected online (fragment of text)
