Detailed Description

Factory for building marginal-distribution configuration objects.

This header defines:

• MarginalConfig, a tagged union of all supported marginal configuration structs,
• MarginalConfigFactory, which derives the appropriate configuration from an existing parameter or observable and a requested MarginalType.

The goal of this factory is to separate:

• extraction of numerical inputs (central values, uncertainties, etc.),
• from actual construction of concrete distributions (handled later by DistributionFactory).

Typical workflow:

auto parameter_proxy = std::make_shared<MyStatParameterProxy>();
MarginalConfigFactory cfg_factory(parameter_proxy);
MarginalConfig cfg = cfg_factory.create(pid, MarginalType::GAUSSIAN);

MarginalConfig

Variant holding any supported marginal configuration object.

Variant of all supported marginal configuration objects.

The active alternative depends on the requested MarginalType and on the information available for the targeted parameter / observable.

The contained type must be compatible with the requested MarginalType.
