ROOT 6.10/09 Reference Guide |
IntervalCalculator is an interface class for a tools which produce RooStats ConfIntervals.
The interface currently assumes that any interval 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 will be extended so that one does not need to use a workspace.
After configuring the calculator, one only needs to ask GetInterval, which will return a 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.
