Legacy Code
TFeldmanCousins is a legacy interface: there will be no bug fixes nor new developments. Therefore it is not recommended to use it in new long-term production code. But, depending on the context, using TFeldmanCousins might still be a valid solution. Consider switching to RooStats for non-trivial cases.
Class to calculate the CL upper limit using the Feldman-Cousins method as described in PRD V57 #7, p3873-3889
The default confidence interval calculated using this method is 90% This is set either by having a default the constructor, or using the appropriate fraction when instantiating an object of this class (e.g. 0.9)
The simple extension to a gaussian resolution function bounded at zero has not been addressed as yet -> ‘time is of the essence’ as they write on the wall of the maze in that classic game ...
VARIABLES THAT CAN BE ALTERED
=> depending on your desired precision: The initial values of fMuMin, fMuMax, fMuStep and fNMax are those used in the PRD:
but there is total flexibility in changing this should you desire.
see example of use in $ROOTSYS/tutorials/math/FeldmanCousins.C
see note about: "Should I use TRolke, TFeldmanCousins, TLimit?" in the TRolke class description.
