| - | * | + | - LC: I mentioned yesterday the list of HEPData Entries which have uncertainty breakdowns. See here: https://gitlab.cern.ch/lhcewkwg/lhcewkwg-vjets/correlations-library/blob/master/RivetAnalysesWithErrorBreakdown.md |
| + | - LC: The info is now propagated into YODA files automatically when downloaded from HEPData (since Nov 2018) | ||
| + | - LC: The error breakdown can be converted to a covariance matrix with these tools quite trivially. Here are some example tools to do so from the YODA files downloaded from HEPData: https://gitlab.cern.ch/lhcewkwg/lhcewkwg-vjets/correlations-library | ||
| + | - LC: Once it is in a cov matrix form, is should be easy to use that for a simplified likelihood, AFAIK? | ||
