Deprecated: RooHistConstraint will be removed in ROOT 6.46, because its functionality is too close to the HistFactory classes. Please constrain the parameters of the HistFactory class ParamHistFunc with one RooPoisson per bin instead, as shown in the rf709_BarlowBeeston tutorial.

The RooHistConstraint implements constraint terms for a binned PDF with statistical uncertainties. Following the Barlow-Beeston method, it adds Poisson constraints for each bin that constrain the statistical uncertainty of the template histogram.

It can therefore be used to estimate the Monte Carlo uncertainty of a fit.

The documentation for this class was generated from the following file:
