Parameters estimated by Maximum Log-Likelihood (MLL) and BIC values for the copula between the pseudo-observations ranks(dam factor) and ranks(Dmax). Left: dam factor = H × VF, = 12378.75; Right: dam factor = Hf, = 1479.85. In both cases the degrees η are estimated by MLL using the tCopula() function of the copula R-package.
