RooSimultaneous: Fitting to Multiple Subranges

ROOT
#1

I have encountered trouble using the Range(“some_named_subrange”) argument with RooSimultaneous::fitTo(…). Fitting the Pdf’s without RooSimultaneous, there is no such problem. I am wondering if others have encountered the same problem. I am happy to provide sample code if desired but figured there might be a simple yes or no on whether fitting to multiple subranges is possible using Range(“subrange”).

Thanks,
Zach

Hello,

I think I am a bit late, but it seems that I have the same problem or similar problem (I am using root 5.28.).

If I apply the command Range(“subrange1”, “subrange2”) in the fitTo function on my RooSimultaneous it seems that always only the first specified subrange from the Range command is fitted. The second subrange seems to be ignored.

Cheers,
Thomas
