چکیده

After proper rescaling and under some technical assumptions, the smallest eigenvalue of a sample covariance matrix with aspect ratio bounded away from 1 converges to the Tracy–Widom distribution. This complements the results on the largest eigenvalue, due to Soshnikov and Péché. PRELIMINARY VERSION

Universality of Local Eigenvalue Statistics for Some Sample Covariance Matrices

Abstract We consider random, complex sample covariance matrices 1 N X ∗X , where X is a p×N random matrix with i.i.d. entries of distribution μ. It has been conjectured that both the distribution of the distance between nearest neighbor eigenvalues in the bulk and that of the smallest eigenvalues become, in the limit N → ∞, p N → 1, the same as that identified for a complex Gaussian distributio...

Large Deviations for Eigenvalues of Sample Covariance Matrices, with Applications to Mobile Communication Systems

We study sample covariance matrices of the form W = (1/n)CC , where C is a k × n matrix with independent and identically distributed (i.i.d.) mean 0 entries. This is a generalization of the so-calledWishart matrices, where the entries ofC are i.i.d. standard normal random variables. Such matrices arise in statistics as sample covariance matrices, and the high-dimensional case, when k is large, ...

Wigner Theorems for Random Matrices with Dependent Entries: Ensembles Associated to Symmetric Spaces and Sample Covariance Matrices

It is a classical result of Wigner that for an hermitian matrix with independent entries on and above the diagonal, the mean empirical eigenvalue distribution converges weakly to the semicircle law as matrix size tends to infinity. In this paper, we prove analogs of Wigner’s theorem for random matrices taken from all infinitesimal versions of classical symmetric spaces. This is a class of model...
