A closed-form estimator for the multivariate GARCH(1,1) model
Multivariate GARCH(1,1) VARMA Temporal Aggregation Es-timation
2013/4/27
We provide a closed-form estimator based on the VARMA representation for the unrestricted multivariate GARCH(1,1). We show that all parameters can be derived using basic linear algebra tools. We show ...
Weighted bootstrap in GARCH models
asymptotic distribution bootstrap confidence region,GARCH model quasi maximum likelihood
2012/11/22
GARCH models are useful tools in the investigation of phenomena, where volatility changes are prominent features, like most financial data. The parameter estimation via quasi maximum likelihood (QMLE)...
Non-Gaussian Quasi Maximum Likelihood Estimation of GARCH Models
Non-Gaussian Quasi Maximum Likelihood Estimation GARCH Models
2010/3/9
The non-Gaussian quasi maximum likelihood estimator is frequently used
in GARCH models with intension to improve the efficiency of the GARCH
parameters. However, the method is usually inconsistent u...

DATA-DRIVEN SCORE TEST OF FIT FOR CONDITIONAL DISTRIBUTION IN THE GARCH(l,l) MODEL
GARCH(1,l) model noise distribution efficient score vector score test BIC Schwarz selection rule
2009/9/18
A data-driven score test for a conditional distribution
in the GARCH(1,l) model is proposed. Conditional distribution assumption
is verified by a score test, obtained from nesting the null
density ...
THE MODIFIED TEMPERED STABLE DISTRIBUTION, GARCH MODELS AND OPTION PRICING
Option pricing GARCH process tempered stable distribution volatility clustering
2009/9/18
We introduce a new variant of the tempered stable distribution,
named the modified tempered stable (MTS) distribution and we develop
a GARCH option pricing model with MTS innovations. This model

Comparison of MCMC Methods for Estimating GARCH Models
Bayesian inference GARCH Gibbs sampler Markov chain Monte Carlo Metropolis-Hastings algorithm
2009/3/6
This paper reviews several MCMC methods for estimating the class of ARCH models, and compare performances of them. With respect to the mixing, efficiency and computational requirement of the MCMC, thi...
CHANGES OF STRUCTURE IN FINANCIAL TIME SERIES AND THE GARCH MODEL
integrated periodogram spectral distribution functional central limit theorem Kiefer-Muller process Brownian bridge sample autocorrelation change point GARCH process long range dependence IGARCH non-stationarity
2009/2/26
In this paper we propose a goodness of fit test that checks the resemblance of the spectral density of a GARCH process to that of the log-returns. The asymptotic behavior of the test statistics are gi...
Modelling Stock Returns with AR-GARCH Processes
autoregressive process GARCH and EGARCH models conditional heteroscedastic variance financial log returns
2009/2/23
Financial returns are often modelled as autoregressive time series with random disturbances having conditional heteroscedastic variances, especially with GARCH type processes. GARCH processes have bee...
