-known GARCH models for density prediction of daily S&P 500 and Nikkei 225 index returns, a comparison is provided between … frequentist and Bayesian estimation. No significant difference is found between the qualities of the forecasts of the whole … density, whereas the Bayesian approach exhibits significantly better left-tail forecast accuracy. …
