Exact Separation of Eigenvalues of Large Dimensional Noncentral Sample Covariance Matrices
Zhidong Bai, Jiang Hu, Jack W. Silverstein +1
Let $ \bbB_n =\frac{1}{n}(\bbR_n + \bbT^{1/2}_n \bbX_n)(\bbR_n + \bbT^{1/2}_n \bbX_n)^* $ where $ \bbX_n $ is a matrix with independent standardized random variables…
