Run the bg only hypothesis test based on the binned Poisson likelihood.
The PoissonBinnedLikelihoodCalculator :
PoissonBinnedLikelihoodCalculator calBG (for the atmospheric background)
PoissonBinnedLikelihoodCalculator calSinal (for the neutrino model such as GZK to be tested)
PoissonBinnedLikelihoodCalculator calNuisanceSingal (for the nuisance signal - like E^-2 against the GZK test)
are generated by the correponding binned data from the files and then executes the methods
provied by ModelTestByPoissonBinnedLikelihoodFactory.
The likeliihood ratio type 5:
5 alternative hypothesis(bg + either signal or nuisance model with floated normalization,
select the one giving larger likelihood)/null hypothesis(bg ONLY)
is calculated by pseudo-experiments with the method
void makeCollectionOfLogLikelihoodRatio(int type=5, int runTimes)
