Dear RooFit experts:
I have a very simple question about RooCategory / RooSimultaneous, in particular i’m referring to slide 7 of:
roofit.sourceforge.net/docs/tuto … ptools.pdf
Is it possible to use extended pdf in RooSimultaneous ?
In other words, is it possible that in the example of slide 7, both pdf_A and pdf_B are extended pdfs ?
Thanks for your support.
Hello Mauro.
I’m trying to do what you mention.
The problem I’m stuck now is the following. I’m trying to fit simultaneously two distributions. The first one with a RooAddPdf Sum (gauss+expo) and the second one with an expo. Although the fit on the expo is fine, the RooAddPdf behaves like Sum = gauss-expo, rather like gauss+expo…
So I’m still in the process trying to figure out if what you mention is doable… If someone of the experts can help…
Cheers,
Stefanos
