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. Webreveals that high-frequency GARCH(1,1) model can be identiﬁed from low-frequency data.
