fitToMin()

RooFitResult * Utils::fitToMin	(	RooAbsPdf *	pdf,
		bool	thorough,
		int	printLevel
	)

Fit PDF to minimum.

Parameters

pdf	The PDF.
thorough	Activate Hesse and Minos
printLevel	-1 = no output, 1 verbose output

Definition at line 19 of file Utils.cpp.

fitToMinBringBackAngles()

RooFitResult * Utils::fitToMinBringBackAngles	(	RooAbsPdf *	pdf,
		bool	thorough,
		int	printLevel
	)

Fit a pdf to the minimum, but keep angular parameters in a range of [0,2pi].

If after an initial fit, a parameter has walked outside this interval, add multiples of 2pi to bring it back. Then, refit. All variables that have unit 'rad' are taken to be angles.

Definition at line 98 of file Utils.cpp.

fitToMinForce()

RooFitResult * Utils::fitToMinForce	(	RooWorkspace *	w,
		TString	name,
		TString	forceVariables = ""
	)

Find the global minimum in a more thorough way.

First fit with external start parameters, then for each parameter that starts with "d" or "r" (typically angles and ratios):

• at upper scan range, rest at start parameters
• at lower scan range, rest at start parameters This amounts to a maximum of 1+2^n fits, where n is the number of parameters to be varied.

Parameters

w	Workspace holding the pdf.
name	Name of the pdf without leading "pdf_".
forceVariables	Apply the force method for these variables only. Format "var1,var2,var3," (list must end with comma). Default is to apply for all angles, all ratios except rD_k3pi and rD_kpi, and the k3pi coherence factor.

< use these variables

< don't use these

Definition at line 138 of file Utils.cpp.

fitToMinImprove()

RooFitResult * Utils::fitToMinImprove	(	RooWorkspace *	w,
		TString	name
	)

Fit to the minimum using an improve method.

The idea is to kill known minima. For this, we add a multivariate Gaussian to the chi2 at the position of the minimum. Ideally it should be a parabola shaped function, but the Gaussian is readily available. A true parabola like in the original IMPROVE algorithm doesn't work because apparently it affects the other regions of the chi2 too much. There are two parameters to tune: the width of the Gaussian, which is controlled by the error definition of the first fit, and the height of the Gaussian, which is set to 16 (=4 sigma). Three fits are performed: 1) initial fit, 2) fit with improved FCN, 3) fit of the non-improved FCN using the result from step 2 as the start parameters. So far it is only available for the Prob method, via the probimprove command line flag.

< define 2 sigma errors. This will make the hesse PDF 2 sigma wide!

TH1F * Utils::histHardCopy	(	const TH1F *	h,
		bool	copyContent = true,
