Abstract
Volatility is an important issue in time series analysis. It has been heavily
investigated in many econometric and financial studies. After a brief review
of univariate volatility models, we will concentrate on multivariate general
autoregressive conditional heteroscedasticity (MGARCH) models, which have
been used to describe and forecast the time-varying variances and covariances
of economic and business data. A crucial step in the MGARCH model building is
the estimation of the linkage matrix in the model. We will propose a new
estimation method, compare it with existing procedures, discuss its merit
including its asymptotic distribution and consistency. The result will be
illustrated with both simulation and real data analysis.
