Forecasting ability of GARCH vs Kalman filter method: evidence from daily UK time-varying beta
Forecasting ability of GARCH vs Kalman filter method: evidence from daily UK time-varying beta
This paper investigates the forecasting ability of four different GARCH models and the Kalman filter method. The four GARCH models applied are the bivariate GARCH, BEKK GARCH, GARCH-GJR and the GARCH-X model. The paper also compares the forecasting ability of the non-GARCH model the Kalman method. Forecast errors based on 20 UK company daily stock return (based on estimated time-vary beta) forecasts are employed to evaluate out-of-sample forecasting ability of both GARCH models and Kalman method. Measures of forecast errors overwhelmingly support the Kalman filter approach. Among the GARCH models GJR model appear to provide somewhat more accurate forecasts than the other bivariate GARCH models.

Abstract
This paper investigates the forecasting ability of four different GARCH models and the Kalman filter method. The four GARCH models applied are the bivariate GARCH, BEKK GARCH, GARCH-GJR and the GARCH-X model. The paper also compares the forecasting ability of the non-GARCH model the Kalman method. Forecast errors based on 20 UK company daily stock return (based on estimated time-vary beta) forecasts are employed to evaluate out-of-sample forecasting ability of both GARCH models and Kalman method. Measures of forecast errors overwhelmingly support the Kalman filter approach. Among the GARCH models GJR model appear to provide somewhat more accurate forecasts than the other bivariate GARCH models.
