GARCH Models have become a workhouse in volatility forecasting of financial and monetary market time series. In this … article, we assess the small sample properties in estimation and the performance in volatility forecasting of four competing … methods can be an asset in volatility forecasting, since model parameters are subject to structural change over time and the …

The study aimed at determining a set of superior generalized orthogonal-GARCH (GO-GARCH) models for forecasting time-varying conditional correlations and variances of five foreign exchange rates vis-à-vis the Nigerian Naira. Daily data covering the period 02/01/2009 to 19/03/2015 was used, and...

We empirically assess efficiency gains in volatility estimation when using range-based estimators as opposed to … simple daily ranges and explore the use of these more efficient volatility measures as predictors of daily ranges. The array … forecasts are produced by a realized range based HAR model with a GARCH volatility-of-volatility component. …
