Hi all,
I’ve encountered a very odd problem when I fit a RooExtendedPdf (generated from a RooGenericPdf) using subranges. Let me use nsig, as the variable representing the number of events in the fit and N as the true number of events in the subranges of the dataset. If I use 2 subranges for the fit, nsig=N/2. If I use 3 subranges, nsig=N/3.
I feel I’m missing something rather silly. I’m attaching a piece of unit testing code (PyROOT). Any advice would be greatly appreciated.
