AB - We introduce new estimates and tests of independence in copula models with unknown margins using $\phi $-divergences and the duality technique. The asymptotic laws of the estimates and the test statistics are established both when the parameter is an interior or a boundary value of the parameter space. Simulation results show that the choice of $\chi ^2$-divergence has good properties in terms of efficiency-robustness.
