Unlike other ellipticals that can take up a lot of space in your home gym, the ProForm Carbon HIIT H7 has a vertical design that makes this elliptical better suited for smaller spaces. It's more ...
Abstract: We address structured covariance estimation in elliptical distributions by assuming that the covariance is a priori known to belong to a given convex set, e.g., the set of Toeplitz or banded ...
Abstract: This paper considers the problem of robustly estimating a structured covariance matrix with an elliptical underlying distribution with a known mean. In applications where the covariance ...
