Covariance matrix testing for high dimensional data is a fundamental problem. A large class of covariance test statistics based on certain averaged spectral statistics of the sample covariance matrix are known to obey central limit theorems under the null. However, precise understanding for the power behavior of the corresponding tests under general alternatives remains largely unknown. This paper develops a general method for analyzing the power behavior of covariance test statistics via… Expand

HIGH DIMENSIONAL ASYMPTOTICS OF LIKELIHOOD RATIO TESTS IN THE GAUSSIAN SEQUENCE MODEL UNDER CONVEX CONSTRAINTS
In the Gaussian sequence model Y = μ+ξ, we study the likelihood ratio test (LRT) for testing H0 : μ = μ0 versus H1 : μ ∈K, where μ0 ∈K, and K is a closed convex set in Rn. In particular, we show thatExpand
High dimensional asymptotics of likelihood ratio tests in Gaussian sequence model under convex constraint
In the Gaussian sequence model $Y=\mu+\xi$, we study the likelihood ratio test (LRT) for testing $H_0: \mu=\mu_0$ versus $H_1: \mu \in K$, where $\mu_0 \in K$, and $K$ is a closed convex set inExpand
