Detailed Description

Base interface for negative log-likelihood evaluators.

Implementations receive a parameter vector and return the corresponding negative log-likelihood value. The interface deliberately keeps the parameter layout abstract; concrete implementations are responsible for defining how is split and interpreted.

Constructor & Destructor Documentation

~ILikelihood()

virtual ILikelihood::~ILikelihood ( )

virtualdefault

Virtual destructor for safe polymorphic deletion.

Member Function Documentation

dim()

virtual std::size_t ILikelihood::dim ( ) const

pure virtual

Returns the total dimension of the parameter vector.

Returns

Number of scalar parameters expected by nll.

Implemented in BaseLikelihood, ChiSquaredLikelihood, and WithGaussianConstraints.

get_param_defs()

virtual std::vector< fit_app::ParameterDefinition > ILikelihood::get_param_defs ( ) const

pure virtual

Returns the metadata describing the likelihood parameters.

The returned definitions are expected to follow the same ordering as the parameter vector accepted by nll.

Returns

Ordered list of parameter definitions.

Implemented in BaseLikelihood, and WithGaussianConstraints.

nll()

virtual double ILikelihood::nll ( const std::vector< double > &  theta ) const

pure virtual

Evaluates the negative log-likelihood at a given parameter point.

Parameters

theta

Parameter vector evaluated by the likelihood implementation.

Returns

Negative log-likelihood value associated with theta.

Implemented in BaseLikelihood, ChiSquaredLikelihood, and WithGaussianConstraints.
