WebEstimating GARCH Models: Whento UseWhat? DaHuang 1HanshengWang QiweiYao2,1 1GuanghuaSchoolofManagement,PekingUniversity,Beijing100871,China 2DepartmentofStatistics,LondonSchoolofEconomics,London,WC2A2AE,UK Abstract The class of GARCH models has proved particularly valuable in modelling time series with … WebGARCH can be used for what you call predictions. The question is: predictions of what? Predictions of volatility. The reason why GARCH is useful is because it may better explain the volatility of certain series, particularly in finance. For instance, look at the graph below. It shows daily log differences of S&P 500 series.
