RooStats::ProfileLikelihoodTestStat Class Reference
RooStats

ProfileLikelihoodTestStat is an implementation of the TestStatistic interface that calculates the profile likelihood ratio at a particular parameter point given a dataset.

It does not constitute a statistical test, for that one may either use:

the ProfileLikelihoodCalculator that relies on asymptotic properties of the Profile Likelihood Ratio the Neyman Construction classes with this class as a test statistic the Hybrid Calculator class with this class as a test statistic
