We consider a p-dimensional, centered normal population such that all variables have positive variance σ2 and any correlation coefficient between different is given nonnegative constant ρ < 1. Suppose both the sample size n dimension p tend to infinity with p/n → c > 0. prove limiting spectral distribution of matrix Marcenko-Pastur index scale parameter 1 − ρ. By distributions, we rigorou...
