Fixed support positive-definite modification of covariance matrix estimators via linear shrinkage
Young-Geun Choi, Johan Lim, Anindya Roy +1
In this work, we study the positive definiteness (PDness) problem in covariance matrix estimation. For high dimensional data, many regularized estimators are proposed under structu…
