Contrôle des systèmes de modélisation : un exemple de codage et de traçabilité des données

One can compare Econometrics with an Art which tries to minimize the lag between a quantitative law and a sample of data. Hence, the econometrics teaches us that before to built models, we must built data bank through strict procedures to prevent errors. Our paper presents classical methods to check data bank building and data computing, then we present new encoding methods ("Explicit Sizes Mantissa", "Dual Mantissa", and "Cumulated Indexes Mantissa") which can lead to follow the data through computing. Some can be based on the Information Theory.
