RooProdPdf is an efficient implementation of a product of PDFs of the form.

\[PDF_1 * PDF_2 * ... * PDF_N \]

PDFs may share observables. If that is the case any irreducable subset of PDFS that share observables will be normalized with explicit numeric integration as any built-in normalization will no longer be valid. Alternatively, products using conditional PDFs can be defined, e.g.

\[F(x|y) * G(y) \]

meaning a pdf F(x) given y and a PDF G(y). In this contruction F is only normalized w.r.t x and G is normalized w.r.t y. The product in this construction is properly normalized. If exactly one of the component PDFs supports extended likelihood fits, the product will also be usable in extended mode, returning the number of expected events from the extendable component PDF. The extendable component does not have to appear in any specific place in the list.

RooProdPdf::RooProdPdf ( )

Default constructor.

Referenced by clone().

RooProdPdf::RooProdPdf	(	const char *	name,
		const char *	title,
		Double_t	cutOff = `0`

Dummy constructor.

Definition at line 120 of file RooProdPdf.cxx.

RooProdPdf::RooProdPdf	(	const char *	name,
		const char *	title,
		RooAbsPdf &	pdf1,
		RooAbsPdf &	pdf2,
		Double_t	cutOff = `0`
	)

Constructor with 2 PDFs (most frequent use case).

The optional cutOff parameter can be used as a speed optimization if one or more of the PDF have sizable regions with very small values, which would pull the entire product of PDFs to zero in those regions.

After each PDF multiplication, the running product is compared with the cutOff parameter. If the running product is smaller than the cutOff value, the product series is terminated and remaining PDFs are not evaluated.

There is no magic value of the cutOff, the user should experiment to find the appropriate balance between speed and precision. If a cutoff is specified, the PDFs most likely to be small should be put first in the product. The default cutOff value is zero.

Constructor from named argument list.

fullPdf – Set of 'regular' PDFS that are normalized over all their observables

Argument	Description
Conditional(pdfSet,depSet)	Add PDF to product with condition that it only be normalized over specified observables any remaining observables will be conditional observables

For example, given a PDF F(x,y) and G(y)

RooProdPdf("P","P",G,Conditional(F,x)) will construct a 2-dimensional PDF as follows:

\[P(x,y) = \frac{G(y)}{\int_y G(y)} * \frac{F(x,y)}{\int_x G(x,y)} \]

which is a well normalized and properly defined PDF, but different from the

\[P'(x,y) = \frac{F(x,y)}{\int_y G(y)} / \int_x\int_y F(x,y)*G(y) \]

In the former case the y distribution of P is identical to that of G, while F only is used to determine the correlation between X and Y. In the latter case the Y distribution is defined by the product of F and G.

This P(x,y) construction is analoguous to generating events from F(x,y) with a prototype dataset sampled from G(y)

virtual

Determine which part (if any) of given integral can be performed analytically.

If any analytical integration is possible, return integration scenario code.

RooProdPdf implements two strategies in implementing analytical integrals

First, PDF components whose entire set of dependents are requested to be integrated can be dropped from the product, as they will integrate out to 1 by construction

Second, RooProdPdf queries each remaining component PDF for its analytical integration capability of the requested set ('allVars'). It finds the largest common set of variables that can be integrated by all remaining components. If such a set exists, it reconfirms that each component is capable of analytically integrating the common set, and combines the components individual integration codes into a single integration code valid for RooProdPdf.
