RooSimultaneous with different observables


I’ve been performing simultaenous fits with the class RooSimultaneous to fit similar data from several detectors of an experiment. But one constraint was always that this data had to have the same observable and even the same observable range (at least when using the model to derive a limit via RooStats).

Is it possible to perform a simultaneous fit and limit derivation (hypothesis test with RooStats::FrequentistCalculator) for different datasets using different observables or observable ranges?




You can use different range from the observable using the solution proposed in this old post
