Understand

The determination of Parton Distribution Functions from a finite set of data is a typical example of an inverse problem.

Inverse problems are notoriously difficult to solve, in particular when a robust determination of the uncertainty in the result is needed.
We present a Bayesian framework to deal with this problem and discuss first results from a closure test.
