I am trying to plot the fit results of a 2D RooSimultaneous fit,
so I have tried to mix these two tutorials
and write something like:
RooAbsPdf* simPdfx = simPdf.createProjection(y) ;
but the PDF shows the wrong normalization (maybe because it is integrated over too many dimensions ?)
This seems to be a common problem that does not have an “official” answer (see posts below) so it’d be really helpful to have some instructions
