Hello a theoretical question regarding TMVA. Can I have for background a root file that the variables inside the tree have different number of events? or there will be some issue?
cheers
Hi,
No this is not possible now. Each feature (variable) passed to TMVA must have the same number of events, we do not support (yet) missing events.
A possible workaround could be to assign a specific value for these missing events
