1. What contributions have the authors mentioned in the paper "Data and model uncertainties in complex aerospace engineering systems" ?
Then, the non-parametric probabilistic model is introduced with the same uncertainty level in order to study the sensitivity of the response with respect to the model and the data uncertainties.
