A note on a Mar?enko-Pastur type theorem for time series

Author:

Journal:
Statistics & Probability Letters


Issue Date:
2012


Abstract(summary):

In this note we develop an extension of the Mar?enko-Pastur theorem to time series model with temporal correlations. The limiting spectral distribution (LSD) of the sample covariance matrix is characterised by an explicit equation for its Stieltjes transform depending on the spectral density of the time series. A numerical algorithm is then given to compute the density functions of these LSD’s.
