Exhaustive Structure Learning of R-Vine Copula Models for Analyzing Multiband Spectrum Utilization in Mobile Communications

IEEE Access
Accurate modeling of multiband spectrum utilization is essential for data-driven spectrum management and refarming in mobile communication systems. However, the bounded and non-Gaussian nature of Resource Block (RB) utilization, together with complex ...

Factor Copula through a vine structure

, 2012
Copula functions have been widely used in actuarial science, finance and econometrics. Though multivariate copulas allow for a flexible specification of the dependence structure of economic variables, they are not particularly tempting in high dimensional contexts.
