Hello,
did the proposal help?
I’m having the same problem as Frederico, and even adding
RooFit::Extended()
RooFit::FitOptions( RooFit::Extended() ) to the RooMcStudy object still leads to the same error.
However, when I’m just validating my models in RooSimultaneous separately it works. The error just shows up when I’m trying to validate the combined model.
Thankful for every help,
Dennis
