### From Coddeau

Nexus Pure Mathematics, Applications of Mathematics, Economics, **Econometrics**.

Econometrics includes the use of mathematical models to describe economic relationships, testing the validity of such hypotheses (statistical inference), estimating the parameters in order to get an appreciation of the strength of the influences of the different variables (correlation, cross-section analysis, regression analysis, time-series analysis). Sets of these kind models are used to make macroeconomic forecasts.
