fact tests for general GARCH asymmetry,. …In this paper I present two new Lagrange multiplier test statistics designed for testing the null of GARCH (1 …,1), against the alternative of asymmetric GARCH. For one test the alternative is the generalized QARCH (1,1) model of Sentana …

This paper investigates the presence of asymmetric GARCH effects in a number of equity return series, and compare the … modeling performance of seven different conditional variance models, within the parametric GARCH class of models. The data … conditional variance. In the paper I also introduce three new procedures for asymmetry testing. The proposed LM tests, which are …

, and, although it outperforms representative GARCH models, it does so with greater complexity and data intensiveness that … may not be worthwhile relative to GARCH's simplicity and flexibility. …

We consider estimates of the parameters of GARCH models of daily financial returns, obtained using intra-day (high … not exist. In particular, we consider estimation in this way of an ARCH approximation, and obtain GARCH parameters by a … estimés des paramètres des modèles GARCH pour les rendements financiers journaliers, qui sont obtenus à l'aide des données …

GARCH models have been successful in modeling financial returns. Still, much is to be gained by incorporating a … and realized measures of volatility. The Realized GARCH framework nests most GARCH models as special cases and is, in many … ways, a natural extension of standard GARCH models. We pay special attention to linear and log-linear Realized GARCH …
