A class for performing a hypothesis test inversion by scanning the hypothesis test results of a HypoTestCalculator for various values of the parameter of interest.

By looking at the confidence level curve of the result, an upper limit can be derived by computing the intersection of the confidence level curve with the desired confidence level. The class implements the RooStats::IntervalCalculator interface, and returns a RooStats::HypoTestInverterResult. The result is a SimpleInterval, which via the method UpperLimit() returns to the user the upper limit value.

Scanning options

The HypoTestInverter implements various options for performing the scan.

HypoTestInverter::RunFixedScan will scan the parameter of interest using a fixed grid.
HypoTestInverter::SetAutoScan will perform an automatic scan to find optimally the curve. It will stop when the desired precision is obtained.
HypoTestInverter::RunOnePoint computes the confidence level at a given point.

CLs presciption

The class can scan the CLs+b values or alternatively CLs. For the latter, call HypoTestInverter::UseCLs().
