ROOT 6.10/09 Reference Guide |
ToyMCSampler is an implementation of the TestStatSampler interface.
It generates Toy Monte Carlo for a given parameter point and evaluates a TestStatistic.
For parallel runs, ToyMCSampler can be given an instance of ProofConfig and then run in parallel using proof or proof-lite. Internally, it uses ToyMCStudy with the RooStudyManager.

This is the generate function to use in the context of the ToyMCSampler instead of the standard RooAbsPdf::generate(...).
It takes into account whether the number of events is given explicitly or whether it should use the expected number of events. It also takes into account the option to generate a binned data set (ie RooDataHist).

This method generates a toy data set for the given parameter point taking global observables into account.
The values of the generated global observables remain in the pdf's variables. They have to have those values for the subsequent evaluation of the test statistics.

This is the main function for serial runs.
It is called automatically from inside GetSamplingDistribution when no ProofConfig is given. You should not call this function yourself. This function should be used by ToyMCStudy on the workers (ie. when you explicitly want a serial run although ProofConfig is present).
Make sure the cache is clear. It is important to clear it hear, because the cache might be invalid even when just the firstPOI was changed, for which no accessor has to be called. (Fixes a bug when ToyMCSampler is used with the Neyman Construction)
