Robustness test econometrics
WebA properly designed sensitivity analysis can be a powerful modeling tool that contributes to an understanding of the relationships between the assumptions of an economic model and its results. Moreover, such an analysis can help validate the model’s predictions even given uncertainty about its assumptions. An incorrectly designed sensitivity ...
