Andersen and Bollerslev (1997), henceforth AB97, suggest that an important limitation of the work of DN is to neglect a possible daily periodic component usually documented in high-frequency time-series. In presence of strong intraday
WebA typical feature of the GARCH family models is that the long run volatility forecast con-verges to a constant level. An exception is the Spline-GARCH model of Engle and Rangel (2008) that allows the unconditional variance to change with time as an exponential spline and the high frequency component to be represented by a unit GARCH process. WebHigh Frequency Multiplicative Component GARCH♣* Robert F. Engle*, Magdalena E. Sokalska** and Ananda Chanda*** August 2, 2005 Abstract This paper proposes a new way of modeling and forecasting intraday returns. We decompose the volatility of high frequency asset returns into components that may be easily interpreted and estimated.
