Résumé
This paper investigates models of stochastic dependence with geostatistical tools.Specifically, we use copulas to propose new models of stochastic spatial tools such as variograms,correlograms and the madograms. Copula versions of covariograms are provided both in secondstationnary and intrinsic frameworks. Moreover, some usual families of models of variograms areclarified with the corresponding parameters.
