In this paper, we consider the … NettetAbstract. The density function of the limiting spectral distribution(LSD) of sample covariance matrices is widely used in large scale statistical inference when the sample size and dimension both tend to infinity.

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.
