The RooStats::HistFactory::Measurement class can be used to construct a model by combining multiple RooStats::HistFactory::Channel objects.

It also allows to set some general properties like the integrated luminosity, its relative uncertainty or the functional form of constraints on nuisance parameters.

◆ CollectHistograms()

void RooStats::HistFactory::Measurement::CollectHistograms ( )

The most common way to add histograms to channels is to have them stored in ROOT files and to give HistFactory the location of these files.

This means providing the path to the ROOT file and the path and name of the histogram within that file. When providing these in a script, HistFactory doesn't load the histogram from the file right away. Instead, once all such histograms have been supplied, one should run this method to open all ROOT files and to copy and save all necessary histograms.

◆ writeToFile()

void RooStats::HistFactory::Measurement::writeToFile ( TFile * file )

A measurement, once fully configured, can be saved into a ROOT file.

This will persitify the Measurement object, along with any channels and samples that have been added to it. It can then be loaded, potentially modified, and used to create new models.

Write every histogram to the file. Edit the measurement to point to this file and to point to each histogram in this file Then write the measurement itself.
