Constructor & Destructor Documentation

◆ MorphCacheElem()

RooIntegralMorph::MorphCacheElem::MorphCacheElem	(	RooIntegralMorph &	self,
		const RooArgSet *	nsetIn
	)

Construct of cache element, copy relevant input from RooIntegralMorph, create the cdfs from the input p.d.fs and instantiate the root finders on the cdfs to perform the inversion.

Definition at line 244 of file RooIntegralMorph.cxx.

◆ ~MorphCacheElem()

RooIntegralMorph::MorphCacheElem::~MorphCacheElem ( )

Destructor.

Definition at line 280 of file RooIntegralMorph.cxx.

Member Function Documentation

◆ binX()

Int_t RooIntegralMorph::MorphCacheElem::binX ( Double_t x )

protected

Return the bin number enclosing the given x value.

Definition at line 314 of file RooIntegralMorph.cxx.

◆ calculate()

void RooIntegralMorph::MorphCacheElem::calculate ( TIterator * iter )

Calculate shape of p.d.f for x,alpha values defined by dIter iterator over cache histogram.

Definition at line 325 of file RooIntegralMorph.cxx.

◆ calcX()

Double_t RooIntegralMorph::MorphCacheElem::calcX	(	Double_t	y,
		Bool_t &	ok
	)

protected

Calculate the x value of the output p.d.f at the given cdf value y.

The ok boolean is filled with the success status of the operation.

Definition at line 292 of file RooIntegralMorph.cxx.

◆ containedArgs()

RooArgList RooIntegralMorph::MorphCacheElem::containedArgs ( Action action )

virtual

Return all RooAbsArg components contained in this cache.

Reimplemented from RooAbsCachedPdf::PdfCacheElem.

Definition at line 224 of file RooIntegralMorph.cxx.

◆ fillGap()

void RooIntegralMorph::MorphCacheElem::fillGap	(	Int_t	ixlo,
		Int_t	ixhi,
		Double_t	splitPoint = `0.5`
	)

protected

Fill all empty histogram bins between bins ixlo and ixhi.

The value of 'splitPoint' defines the split point for the recursive division strategy to fill the gaps If the midpoint value of y is very close to the midpoint in x, use interpolation to fill the gaps, otherwise the intervals again.

Definition at line 447 of file RooIntegralMorph.cxx.

◆ findRange()

void RooIntegralMorph::MorphCacheElem::findRange ( )

protected

Determine which range of y values can be mapped to x values from the numeric inversion of the input c.d.fs.

Start with a y range of [0.1-0.9] and push boundaries outward with a factor of 1/sqrt(10). Stop iteration if inverted x values no longer change

Definition at line 560 of file RooIntegralMorph.cxx.

◆ interpolateGap()

void RooIntegralMorph::MorphCacheElem::interpolateGap	(	Int_t	ixlo,
		Int_t	ixhi
	)

protected

Fill empty histogram bins between ixlo and ixhi with values obtained from linear interpolation of ixlo,ixhi elements.
