Minimax Rate-optimal Estimation of High-dimensional Covariance Matrices with Incomplete Data()

Missing data occur frequently in a wide range of applications. In this paper, we consider estimation of high-dimensional covariance matrices in the presence of missing observations under a general missing completely at random model in the sense that the missingness is not dependent on the values of...
