void TGo4Fitter::RebuildAll ( Bool_t ForceBuild = kFALSE )

protected

Update all data objects and model components according to current parameters values.

Only those objects will be recalculated, which parameters were changed after last recalculation. If ForceBuild flag is set (default = kFALSE), all objects will be recalculated anyway.

RemoveData()

TGo4FitData * TGo4Fitter::RemoveData	(	const char *	DataName,
		Bool_t	IsDel = kFALSE )

Remove data object from fitter.

If IsDel flag is set, object will be destroyed, otherwise (by default) function return pointer on this object.

RemoveModel()

TGo4FitModel * TGo4Fitter::RemoveModel	(	const char *	ModelName,
		Bool_t	IsDel = kFALSE )

Remove model component from fitter.

If IsDel flag specified, component is delete, otherwise (by default) function return pointer on this model component.

SetFitFunctionType()

void TGo4Fitter::SetFitFunctionType ( Int_t iFitFunctionType )

inline

Set fitted function type for minimization.

Possible values are: TGo4Fitter:ff_least_squares = 0 sum of difference squares between model and data; TGo4Fitter:ff_chi_square = 1 standard chi-square sum TGo4Fitter:ff_chi_Pearson = 2 Pearson chi-square for Poisson statistic TGo4Fitter:ff_chi_Neyman = 3 modified Neyman chi-square for Poisson statistic TGo4Fitter:ff_chi_gamma = 4 modified chi-square for Poisson statistic TGo4Fitter:ff_ML_Poisson = 5 -2Ln from maximum likelihood function for Poisson statistic TGo4Fitter:ff_user = 6 user function User function type should not be specified directly, but using SetUserFitFunction() method. More information about fit function types can be found in Go4Fit tutorial.

SetGraph()

TGo4FitDataGraph * TGo4Fitter::SetGraph	(	const char *	DataName,

SetMemoryUsage()

void TGo4Fitter::SetMemoryUsage

(

Int_t

iMemoryUsage

)

Set value of memory usage.

This parameter can be: 0 - no additional memory will be allocated in buffers 1 - buffers will be allocated only for data objects 2 - buffers will be used for all data and models objects 3 - individual setup for data and model objects will be used for memory allocations

SetUserFitFunction()

void TGo4Fitter::SetUserFitFunction ( TUserFitFunction iFunc )

inline

Set user-defined fitted function.

Function should be global and has following signature: Double_t (TUserFitFunction)(Int_t, Double_t, Double_t*) First parameter - number of points, Second - array of data points, Third - array of model points. Function should return value, which will be MINIMIZED by fitter. If necessary maximization, fit function should return negative value.
