Detailed Description

Builds distribution-configuration objects from parameters or observables.

This factory converts a statistical object description into a configuration suitable for a concrete marginal distribution.

Current implemented policies:

• For a ParamId:
  • GAUSSIAN -> centered at parameter value, width = combined uncertainty
  • FLAT -> interval chosen so that the flat std matches the combined uncertainty
• For a BinnedObservableId:
  • GAUSSIAN -> mean fixed to 0, width = combined observable uncertainty
  • FLAT -> symmetric interval around 0 with matching std

Current non-implemented cases:

• HALF_GAUSSIAN
• LIKELIHOOD

Those currently raise exceptions in the implementation.

Constructor & Destructor Documentation

MarginalConfigFactory()

MarginalConfigFactory::MarginalConfigFactory ( std::shared_ptr< IStatParameterProxy >  parameter_proxy )

explicit

Constructs the factory with its parameter-access port.

The concrete adapter is selected by the composition root (typically StatisticInterface) and forwarded by StatisticManager. The factory therefore remains independent of parameter-storage infrastructure.

Parameters

parameter_proxy

Read-only statistical parameter port.

Exceptions

std::invalid_argument

if parameter_proxy is null.

Member Function Documentation

create() [1/3]

MarginalConfig MarginalConfigFactory::create	(	ExperimentObs	pid,
		MarginalType	marginal
	)		const

Builds a vector of marginal configurations from a binned observable identifier.

Current convention for observables:

• the marginal is centered at 0,
• the spread is derived from the observable combined uncertainty.

This is useful when the marginal describes a fluctuation / nuisance-like variable rather than an absolute physical central value.

Parameters

pid	ExperimentObs observable identifier.
marginal	Requested marginal family.

Returns

A MarginalConfig variant containing the matching config type.

Exceptions

std::runtime_error	for currently unsupported marginals.
std::invalid_argument	if the marginal type is unknown.

Definition at line 68 of file MarginalConfigFactory.cpp.

create() [2/3]

MarginalConfig MarginalConfigFactory::create	(	ParamId	pid,
		MarginalType	marginal
	)		const

Builds a marginal configuration from a parameter identifier.

The parameter is queried through the injected IStatParameterProxy port.

Current behavior:

• MarginalType::GAUSSIAN returns GaussianMarginalCfg{mu, sigma}
• MarginalType::FLAT returns FlatMarginalCfg with bounds , so that the flat distribution has standard deviation

Parameters

pid	Parameter identifier.
marginal	Requested marginal family.

Returns

A MarginalConfig variant containing the matching config type.

Exceptions

std::runtime_error	for currently unsupported marginals.
std::invalid_argument	if the marginal type is unknown.

Definition at line 20 of file MarginalConfigFactory.cpp.

create() [3/3]

MarginalConfig MarginalConfigFactory::create	(	ParamId	pid,
		MarginalType	marginal,
		const NuisanceSpec &	spec
	)		const

Builds a parameter marginal while honoring an explicit nuisance specification.

For a flat nuisance, the configured support is taken directly from spec.bounds instead of being reconstructed from the parameter standard deviation. Other marginal families retain the standard parameter-derived configuration.

Parameters

pid	Parameter identifier.
marginal	Effective marginal family after default/user resolution.
spec	Effective nuisance specification associated with pid.

Returns

A marginal configuration compatible with MarginalFactory.

Exceptions

std::invalid_argument

if the specification block/code does not match pid, or if flat bounds are non-finite or not strictly ordered.
