WebGARCH models and smoothing methods. GARCH models enable statistical modelling of volatility. A recent development in this area has been the use of smooth transition models (see Hagerud, 1997, and González-Rivera, 1998). These models allow a parameter to vary over time as a continuous function of a transition variable.
