Abstract
Conditioning simulations by using kriging was proposed by G. Matheron at the start of the 70s. The following presentation only recalls results that should be already well-known.
Simulation methods enable us to construct realizations of RF having a fixed covariance K. In practice, the values z (xα) at the data points xα are known and we dictate that at these points the RF Z and its simulations must coincide. The conditioning method by kriging makes it possible to carry out a conditional simulation into two steps: construction of a nonconditional simulation, then the conditioning kriging. In the general case, simulations obtained in this way have the specified covariance K and are such that at the data points t(xα) = z(xα). In addition, for a RF having multigaussian distribution, the conditional distribution Z(x)|Z(xα1), …, Z(xαn) is reproduced.
