LauAbsFitter::ClassDef	(	LauAbsFitter	,
		0
	)

private

virtual const TMatrixD& LauAbsFitter::covarianceMatrix ( ) const

pure virtual

Retrieve the fit covariance matrix.

Implemented in LauMinuit.

virtual void LauAbsFitter::fixSecondStageParameters ( )

pure virtual

Fix parameters marked as "second stage".

Implemented in LauMinuit.

virtual LauFitObject* LauAbsFitter::getFitObject ( )

pure virtual

Get the object that controls the calculation of the likelihood.

Implemented in LauMinuit.

virtual void LauAbsFitter::initialise	(	LauFitObject *	fitObj,
		const std::vector< LauParameter * > &	parameters
	)

pure virtual

Initialise the fitter, setting the information on the parameters.

Parameters

[in]	fitObj	the object that controls the likelihood calculation
[in]	parameters	the list of parameters of the fit

Implemented in LauMinuit.

virtual const FitStatus& LauAbsFitter::minimise ( )

pure virtual

Perform the minimisation of the fit function.

Returns: the status code of the fit and the minimised value

Implemented in LauMinuit.

virtual UInt_t LauAbsFitter::nFreeParameters ( ) const

pure virtual

Get the number of floating fit parameters.

Implemented in LauMinuit.

virtual UInt_t LauAbsFitter::nParameters ( ) const

pure virtual

Get the total number of fit parameters.

Implemented in LauMinuit.

LauAbsFitter& LauAbsFitter::operator= ( const LauAbsFitter & rhs )

private

Copy assignment operator - private and not implemented.

virtual void LauAbsFitter::releaseSecondStageParameters ( )

pure virtual

Release parameters marked as "second stage".

Implemented in LauMinuit.

virtual Bool_t LauAbsFitter::twoStageFit ( ) const

pure virtual

Determine whether the two-stage fit is enabled.

Implemented in LauMinuit.

virtual void LauAbsFitter::twoStageFit ( Bool_t doTwoStageFit )

pure virtual

Turn on or off the two stage fit.

The two-stage fit allows certain parameters to be fixed in one stage and floated in another stage of the fit. Can be used, for example, in a CP fit where the CP-parameters are fixed to zero in the first stage (while the CP-average parameters are determined), then floated in the second.

Parameters

[in] doTwoStageFit boolean specifying whether or not the two-stage fit should be enabled

Implemented in LauMinuit.

virtual void LauAbsFitter::updateParameters ( )

pure virtual

Update the values and errors of the parameters based on the fit minimum.

Implemented in LauMinuit.

virtual Bool_t LauAbsFitter::useAsymmFitErrors ( ) const

pure virtual

Determine whether calculation of asymmetric errors is enabled.

Implemented in LauMinuit.

virtual void LauAbsFitter::useAsymmFitErrors ( Bool_t useAsymmErrors )

pure virtual

Turn on or off the computation of asymmetric errors (e.g. MINOS routine in Minuit)

Parameters

[in] useAsymmErrors boolean specifying whether or not the computation of asymmetric errors is enabled

Implemented in LauMinuit.
