In this thesis GARCH(11)-models for the analysis of nancial time series are investigated Firstsu cient and necessary conditions will be given for the process to have a stationary solution Then asymptotic results for relevant estimators will be derived and used to develop parametrictests
9 But the process is not really mysterious For any set of parameters wa b and a starting estimate for the variance of the first observation which is often taken to be the observed variance of the residuals it is easy to
We study in depth the properties of the GARCH(11) model and the assump-tions on the parameter space under which the process is stationary In particular weprove ergodicity and strong stationarity for the conditional variance (squared volatil-ity) of the process

The focus on Garch(11) is for simplicity of exposition only The principle below allows one to improve estimation of the parameters of any scale process vn Let us say a few words on parameter estimation in this model The returns rn n = 1 N are observable the volatilities vnare not
GARCH (Generalized AutoRegressive Conditional Heteroscedastic) processes are dynamic models of conditional standard devi- ations and correlations This tutorial begins with univariate GARCH models of conditional variance including univariate APARCH (Asymmetric Power ARCH) models that feature the leverage effect often seen in asset returns
The GARCH (11) model is perhaps the most popular model in the GARCH-type models and is often used in many empirical studies in the field of finance The model implies that today’s variance can be
