Detailed Description
Helper used to transform collections of identifiers into correlation matrices/maps.
This class provides convenience utilities for building dense or associative correlation representations from collections of:
- parameters (ParamId),
- experiment-scoped observables (ExperimentObs),
- observables identified by BinnedObservableId together with an experiment name.
Internally, all correlation coefficients are queried through an IStatCorrelationProxy using CorrelationProvider::CorrelationType::COMBINED.
For parameter collections, the output is built directly from the parameter IDs.
For observable collections, two usage modes are supported:
- explicit mode using ExperimentObs,
- convenience mode for a homogeneous collection of BinnedObservableId belonging to the same experiment, by passing the experiment name separately.
The class also provides a filtering helper check_if_corr(...) for parameters, which keeps only parameters with a strictly positive combined standard uncertainty as returned by the parameter proxy.
