Deprecated: RooParamHistFunc will be removed in ROOT 6.46, because its functionality is too close to the HistFactory classes. Please use the HistFactory class ParamHistFunc instead, multiplying it with a RooHistFunc, as shown in the rf709_BarlowBeeston tutorial.

A histogram function that assigns scale parameters to every bin. Instead of the bare bin contents, it therefore yields:

\[ \gamma_{i} * \mathrm{bin}_i \]

The \( \gamma_i \) can therefore be used to parametrise statistical uncertainties of the histogram template. In conjunction with a constraint term, this can be used to implement the Barlow-Beeston method. The constraint can be implemented using RooHistConstraint.

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