Forecasting Stock Market Volatility with Regime-Switching GARCH Models

Marcucci, Juri - In: Studies in Nonlinear Dynamics & Econometrics 9 (2005) 4, pp. 1145-1145

risk-management loss functions. Under statistical losses, we use both tests of equal predictive ability of the Diebold … under two subjective VaR-based loss functions. The empirical analysis demonstrates that MRS-GARCH models do really …-based risk-management loss functions. In particular, all tests reject the presence of a better model than the MRS-GARCH with …

Correspondence On the Selection of Error Measures for Comparisons Among Forecasting Methods

Armstrong, JS; Fildes, Robert - EconWPA - 2004

Clements and Hendry (1993) proposed the Generalized Forecast Error Second Moment (GFESM) as an improvement to the Mean Square Error in comparing forecasting performance across data series. They based their conclusion on the fact that rankings based on GFESM remain unaltered if the series are...

Generalized (Cross) Spectral Tests for Optimal Forecasts and Conditional Predictive Ability Under Generalized Loss Functions

Lee, Tae-Hwy; Hong, Yongmiao - Econometric Society - 2004

Under the squared error loss, the optimal forecast is the conditional mean, and the one-step forecast error is a martingale difference (MD). The one-step forecast error forms the conditional moment condition obtained from the loss derivative with respect to the forecast. Similarly, under a...

The Macroeconomic Loss Function: A Critical Note

Mayer, Thomas - Economics Department, University of California-Davis - 2003

The standard loss function gives the same weight to positive and negative deviations from the output and inflation targets. This short note criticizes this symmetry assumption. If the period covered is long enough output growth in excess of the target, and often also inflation rates that are...
