A blocking and regularization approach to high dimensional realized covariance estimation
Hautsch, Nikolaus; Kyj, Lada M.; Oomen, Roel C.A.
We introduce a regularization and blocking estimator for well-conditioned high-dimensional daily covariances using high-frequency data. Using the Barndorff-Nielsen, Hansen, Lunde, and Shephard (2008a) kernel estimator, we ...
