I am trying to integrate a RooNDKeysPDF (2D) over a specified range in the two variables:
I noticed that as soon as I specify a range for the integration, with a code like the following,
the code falls back to the numeric integration, which poses some performance issues in my case.
However I can see that the analytical integral exist, so I am wondering if that is the expected behaviour.
Attached is an example code. Can anyone advise if and how I can achieve analytic integration in this case?
Thanks in advance
