The Essex Centre for Macro and Financial Econometrics brings together academic and industry expertise from inside and outside the University of Essex to research and help solve important issues in financial markets.

Seminar abstract

In this presentation the authors present new results for a new parametrization of correlation matrices, that can be viewed as a generalization of the Fisher transformation of a correlation coefficient.

The parametrization has desirable properties and can be used to generate random correlation matrices, as we illustrate.

They also present results for block correlation matrices, for which a canonical representation greatly simplify estimation in static models. They also use the canonical representation to introduce a new type of multivariate GARCH models. Several results will be visualized using the Julia Programming language.
