WebApr 13, 2024 · Bollerslev extended the idea with Generalized ARCH models (GARCH) by adding a lagged variance term in the conditional equation. This model became popular since it has few parameters, can generally explain the major stylised facts of returns (Cont, 2001) and has been empirically shown to produce forecasts with good accuracy (Taylor, 2007). WebApr 13, 2024 · The GARCH model is one of the most influential models for characterizing and predicting fluctuations in economic and financial studies. However, most traditional GARCH models commonly use daily frequency data to predict the return, correlation, and risk indicator of financial assets, without taking data with other frequencies into account. … Weberalized ARCH (GARCH) model that Bollerslev (1986) and Taylor (1986) proposed independently of each other.
