A multiple testing approach to the regularisation of large sample correlation matrices

Bailey, Natalia; Pesaran, M. Hashem; Smith, L. Vanessa - 2015

This paper proposes a regularisation method for the estimation of large covariance matrices that uses insights from the multiple testing (MT) literature. The approach tests the statistical significance of individual pair-wise correlations and sets to zero those elements that are not...

Aggregation in Large Dynamic Panels

Pesaran, M. Hashem - 2011

This paper considers the problem of aggregation in the case of large linear dynamic panels, where each micro unit is potentially related to all other micro units, and where micro innovations are allowed to be cross sectionally dependent. Following Pesaran (2003), an optimal aggregate function is...

Modelling Volatilities and Conditional Correlations in Futures Markets with a Multivariate T Distribution

Pesaran, Bahram; Pesaran, M. Hashem - 2021

This paper considers a multivariate t version of the Gaussian dynamic conditional correlation (DCC) model proposed by Engle (2002), and suggests the use of devolatized returns computed as returns standardized by realized volatilities rather than by GARCH type volatility estimates. The t-DCC...
