RooStats::HypoTestCalculator Class Referenceabstract

HypoTestCalculator is an interface class for a tools which produce RooStats HypoTestResults.

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

• a model for the null,
• a model for the alternate,
• a data set,
• a set of parameters of which specify the null (including values and const/non-const status), and
• a set of parameters of which specify the alternate (including values and const/non-const status).

The interface allows one to pass the model, data, and parameters via a workspace and then specify them with names. The interface will be extended so that one does not need to use a workspace.

After configuring the calculator, one only needs to ask GetHypoTest, which will return a HypoTestResult 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.
