On the eigenvectors of large dimensional sample covariance matrices

Let {vij}, i, J = 1,2, ..., be i.i.d. random variables, and for each n let Mn = (1/s)VnVnT, where Vn = (vij), i = 1, 2, ..., n, j = 1, 2, ..., s = s(n), and n/s --> y > 0 as n --> [infinity]. Necessary and sufficient conditions are given to establish the convergence in distribution of certain random variables defined by Mn. When E(v114) < [infinity] these variables play an important role toward understanding the behavior of the eigenvectors of this class of sample covariance matrices for n large.
