I’m using ROOT 5.25/02. I ran the roostats/rs500d macro to create a workspace with a gaussian signal over a flat background. This creates a model file which is the default input file for the roostats/rs504 macro. The rs504 macro runs some pseudo experiments and calculates the signal significance.
As the calculation was somewhat slow, I wanted to generate binned data which could help to speed things up. So I changed line 78 and 81 in rs504 and added the parameter “Binned(true)” to the argument list of the RooMCStudy constructor.
However, re-running the pseudo experiments with these changes yields a totally different average significance (0.78sigma instead of 29sigma).
What am I doing wrong?
Thanks and cheers,
