Standard demo of the ProfileInspector class StandardProfileInspectorDemo

This is a standard demo that can be used with any ROOT file prepared in the standard way. You specify:

  • name for input ROOT file
  • name of workspace inside ROOT file that holds model and data
  • name of ModelConfig that specifies details for calculator tools
  • name of dataset

With default parameters the macro will attempt to run the standard hist2workspace example and read the ROOT file that it produces.

The actual heart of the demo is only about 10 lines long.

The ProfileInspector plots the conditional maximum likelihood estimate of each nuisance parameter in the model vs. the parameter of interest. (aka. profiled value of nuisance parameter vs. parameter of interest) (aka. best fit nuisance parameter with p.o.i fixed vs. parameter of interest)
