RooDataProjBinding Class Reference

adaptor that projects a real function via summation of states provided in a dataset.

The real function must be attached to the dataset before creating this binding object.

If the dataset only contains category variables, the summation is optimized performing a weighted sum over the states of a RooSuperCategory that is constructed from all the categories in the dataset
