Cokriging allows the use of data on correlated variables in order to enhance the estimation of a primary variable or more generally to enhance the estimation of all variables. However, in order to apply the estimation procedure, some problems must be solved: the variogram matrix must be conditionally negative definite and it is necessary to model the cross-variogram. The aim of this paper is to present a flexible solution in order to solve the mentioned problems. A case study has been presented.
