A multi-parameters formula, adapted to each encountered situation is generated (power or multi-linear function) linked with statistical indicators in order to check the quality of the created formula (statistical model). It is possible to temporarily disable one or more parameters, or one or more projects, in order to perform different simulations and to keep the best one.

The software automatically calculates the least coherent project (step by step if there are several incoherent projects) to check that there is no risk of developing a biased model.

Step 3 : Estimation of a new project
