This cdf estimator assumes the cdf of variable Z is Gaussian, and does account for secondary variables. The mean and variance of the Gaussian cdf are estimated by cokriging.
|covariance_set||is a model of Covariance Set|
|kriging_constraints||is model of Kriging Constraint. It is set by default to OK_constraints<tnt_lib>|
|matrix_lib||defines the library of linear algebra to be used. The default value is tnt_lib, the TNT library.|
u is the location at which the Gaussian conditional cdf is estimated. The function returns 0 if no problem occurred.
