ESD of singular values of random band matrices; Marchenko-Pastur law and more

open access: yes, 2016
We consider the limiting spectral distribution of matrices of the form $\frac{1}{2b_{n}+1} (R + X)(R + X)^{*}$, where $X$ is an $n\times n$ band matrix of bandwidth $b_{n}$ and $R$ is a non random band matrix of bandwidth $b_{n}$.

Necessary and sufficient conditions for the Marcĕnko–Pastur law for sample correlation matrices

open access: yes
Necessary and sufficient conditions are found for the Marcĕnko–Pastur law to hold for a fairly general class of sample correlation matrices under different moment conditions.Marcĕko–Pastur law; Sample covariance matrix; Sample correlation matrix ...

Marčenko-Pastur law for Kendall’s tau

open access: yes, 2017
We prove that Kendall’s Rank correlation matrix converges to the Marčenko Pastur law, under the assumption that observations are i.i.d random vectors X[subscript 1 ]…,X[subscript n] with components that are independent and absolutely continuous with ...
