RooStats::CombinedCalculator Class Referenceabstract

CombinedCalculator is an interface class for a tools which can produce both RooStats HypoTestResults and ConfIntervals.

The interface currently assumes that any such calculator can be configured by specifying:

The interface allows one to pass the model, data, and parameters via a workspace and then specify them with names. The interface also allows one to pass the model, data, and parameters without a workspace (which is created internally).

After configuring the calculator, one only needs to ask GetHypoTest() (which will return a HypoTestResult pointer) or GetInterval() (which will return an ConfInterval pointer).

The concrete implementations of this interface should deal with the details of how the nuisance parameters are dealt with (eg. integration vs. profiling) and which test-statistic is used (perhaps this should be added to the interface).

The motivation for this interface is that we hope to be able to specify the problem in a common way for several concrete calculators.
