CERFACS was pleased to welcome Pr. A. Saltelli for a wide interest seminar an Uncertainty Quantification. Pr. Andrea Saltelli’s main disciplinary focus is on sensitivity analysis. The main idea behind sensitivity analysis is to figure out how the uncertainty in the output of a model can be apportioned to different sources of uncertainty in its inputs.
Pr. Saltelli has worked on various fields of application such as physical chemistry, environmental sciences, applied statistics, impact assessment and science for policy. At present he is adjunct professor at the Centre for the Study of the Sciences and the Humanities at University of Bergen. He is currently a visiting fellow at Open Evidence Research at the Universitat Oberta de Catalunya in Barcelona.
The talk was entitled “Are the results from a particular model more sensitive to changes in the model and the methods used to estimate its parameters, or to changes in the data”. It reviewed some principles of sensitivity analysis, good and bad practices, and some practitioners’ insight on when to use what.
