Large sample autocovariance matrices of linear processes with heavy tails

Johannes Heiny, Thomas Mikosch

We provide asymptotic theory for certain functions of the sample autocovariance matrices of a high-dimensional time series with infinite fourth moment. The time series exhibits lin…

Extreme value analysis for the sample autocovariance matrices of heavy-tailed multivariate time series

Richard Davis, Johannes Heiny, Thomas Mikosch +1

We provide some asymptotic theory for the largest eigenvalues of a sample covariance matrix of a p-dimensional time series where the dimension p = p_n converges to infinity when th…
