GammaCombo is a framework to combine measurements in order to compute confidence intervals on parameters of interest. A global likelihood function is constructed from the probability densitiy functions of the input observables, which is used to derive likelihood-based intervals and frequentist intervals based on pseudoexperiments following the Plugin method to handle nuisance parameters.
