“…Notice that c δ is symmetric, that is it is invariant under the permutation of the variables. This provides a new family of absolutely continuous symmetric copulas with given diagonal section enriching previous work on this subject that we discussed, see [2], [8], [9], [10], [11], [12], [18]. We also calculate the maximum entropy copula for diagonal sections that arise from well-known families of bivariate copulas.…”
