RooDLLSignificanceMCSModule Class Reference

RooDLLSignificanceMCSModule is an add-on modules to RooMCStudy that calculates the significance of a signal by comparing the likelihood of a fit fit with a given parameter floating with a fit with that given parameter fixed to a nominal value (usually zero).

The difference in the -log(L) of those two fits can be interpreted as the probability that a statistical background fluctation may result in a signal as large or larger than the signal observed. This interpretation is contingent on underlying normal sampling distributions and a MC study is a good way to test that assumption.
