Multivariate skewed t-distribution with degrees of freedom vector and its application to financial modeling
A modification of multivariate t-distribution with vector of degrees of freedom is suggested: multivariate t-distribution with vector of skewness parameters and vector of degrees of freedom is introduced. A special case of this distribution is already known multivariate skew t-distribution with scalar parameter of degrees of freedom. Application of the constructed distribution in BEKK models is considered.
