RooRandomizeParamMCSModule Class Reference

RooRandomizeParamMCSModule is an add-on modules to RooMCStudy that allows you to randomize input generation parameters.

Randomized generation parameters can be sampled from a uniform or Gaussian distribution. For every randomized parameter, an extra variable is added to RooMCStudy::fitParDataSet() named <parname>_gen that indicates the actual value used for generation for each trial. You can also choose to randomize the sum of N parameters, rather than a single parameter. In that case common multiplicative scale factor is applied to each component to bring the sum to the desired target value taken from either uniform or Gaussian sampling. This latter option is for example useful if you want to change the total number of expected events of an extended p.d.f
