Nettetamong the entries grows with p. As a corollary, we derive the limiting spectral distribution for the large sample covariance matrices Σb n associated with xp. Our results are close to that of [7], [12], and [25]. The paper [7] studies the block independent model for xp where the entries of xp are partitioned into blocks in NettetAs examples we show the existence of the spectral distribution when X is taken to be the appropriate asymmetric Hankel, Toeplitz, circulant and reverse circulant matrices.
