Detailed Description

Calibrated model class.

Member Function Documentation

update()

void update ( )

overridevirtual

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.

Implements Observer.

Reimplemented in Gsr, and MarkovFunctional.

calibrate()

virtual void calibrate ( const std::vector< ext::shared_ptr< CalibrationHelper > > & , OptimizationMethod & method, const EndCriteria & endCriteria, const Constraint & constraint = Constraint(), const std::vector< Real > & weights = std::vector< Real >(), const std::vector< bool > & fixParameters = std::vector< bool >() )

virtual

Calibrate to a set of market instruments (usually caps/swaptions)

An additional constraint can be passed which must be satisfied in addition to the constraints of the model.

Reimplemented in MarkovFunctional.
