Let $$\lambda _1, \ldots , \lambda _n$$λ1,…,λn be random eigenvalues coming from the beta-Laguerre ensemble with parameter $$p$$p, which is a generalization of the real, complex and quaternion Wishart matrices of parameter $$(n,p).$$(n,p). In the case that the sample size $$n$$n is much smaller than the dimension of the population distribution $$p$$p, a common situation in modern data, we approximate the beta-Laguerre ensemble by a beta-Hermite ensemble, which is a generalization of the real… Expand
