Hi all.
I have the following problem and I would be really grateful if someone can give me a hint…
I have a script that performs an extended ml fit in two distributions. All well so far.
When I try to do it in RooSimultaneous way, the result of the first fit is behaving:
instead of RooAddPdf = Gauss + Expo
RooAddPdf = (Gauss + Expo) / 2
Any ideas??
Thanks,
Stefanos
