A multiple testing approach to the regularisation of large sample correlation matrices
Bailey, Natalia; Pesaran, M. Hashem; Smith, L. Vanessa - 2014
This paper proposes a novel regularisation method for the estimation of large covariance matrices, which makes use of insights from the multiple testing literature. The method tests the statistical significance of individual pair-wise correlations and sets to zero those elements that are not...
