<i>L</i><sub>1</sub> Regularization for High-Dimensional Multivariate GARCH Models
The complexity of estimating multivariate GARCH models increases significantly with the increase in the number of asset series. To address this issue, we propose a general regularization framework for high-dimensional GARCH models with BEKK representations, and obtain a penalized quasi-maximum likel...
