# Macro "**modelerbuildSimpleGPEstimWithCov.{{extension}}**"

## Objective

This macro is the one described in [](#modeler_kriging_usage_prediction_global), to create and use a 
simple gaussian process, whose training (`utf_4D_train.dat`) and testing (`utf_4D_test.dat`) database 
can both be found in the document folder of the {{uranie}} installation 
(`${URANIESYS}/share/uranie/docUMENTS`). It uses the global approach, computing the input covariance 
matrix and translating it to the prediction covariance matrix.
