ModelConfig is a simple class that holds configuration information specifying how a model should be used in the context of various RooStats tools.

A single model can be used in different ways, and this class should carry all that is needed to specify how it should be used. ModelConfig requires a workspace to be set.

A ModelConfig holds sets of parameters of the likelihood function that have different interpretations:

Parameter of interest Parameters that are measured (i.e. fitted).
Nuisance parameters Parameters that are fitted, but their post-fit value is not interesting. Often, they might be constrained because external knowledge about them exists, e.g. from external measurements.
Constraint parameters No direct use in RooFit/RooStats. Can be used by the user for bookkeeping.
Observables Parameters that have been measured externally, i.e. they exist in a dataset. These are not fitted, but read during fitting from the entries of a dataset.
Conditional observables Observables that are not integrated when the normalisation of the PDF is calculated. See e.g. rf306_condpereventerrors in the RooFit tutorials.
Global observables Observables that to the fit look like "constant" values, i.e. they are not being fitted and they are not loaded from a dataset, but some knowledge exists that allows to set them to a specific value. Examples: – A signal efficiency measured in a Monte Carlo study. – When constraining a parameter \( b \), the target value ( \( b_0 \)) that this parameter is constrained to:
\[ \mathrm{Constraint}_b = \mathrm{Gauss}(b_0 \, | \, b, 0.2) \]
External constraints Include given external constraints to likelihood by multiplying them with the original likelihood.
