WebOct 17, 2013 · Abstract. This article considers a GARCH process, generally named as GARCH-X, in which the additional covariate is specified as a positive fractionally integrated process. Recent work on MEM, HEAVY, and Realized GARCH models falls in this category. We investigate the asymptotic properties of this process and show how it explains … WebApr 13, 2024 · They used a multivariate GARCH framework and showed that realized covariance estimators performed significantly better than standard estimators. Models that forecast covariance matrices must ensure that the estimates are positive definite.
