Some example of how to deal with (eg. negative) event weights in RooFit.
Specifically, the examples show how to do error calculation for weighted unbinned ML fits.

  • baak_eventweights.pdf is a presentation I've given on the use of event weights in weighted unbinned ML fits in the Atlas statistics forum.
  • The various macros recreate the plots in the presentation.
