RooProdPdf Class Reference

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

\[ \prod_{i=1}^{N} \mathrm{PDF}_i (x, \ldots) \]

.

PDFs may share observables. If that is the case any irreducible subset of PDFs that share observables will be normalised with explicit numeric integration as any built-in normalisation will no longer be valid.

Alternatively, products using conditional PDFs can be defined, e.g.

\[ F(x|y) \cdot G(y), \]

meaning a PDF \( F(x) \) given \( y \) and a PDF \( G(y) \). In this construction, \( F \) is only normalised w.r.t \( x\), and \( G \) is normalised w.r.t \( y \). The product in this construction is properly normalised.

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.

Constructor & Destructor Documentation

◆ RooProdPdf() [1/8]

RooProdPdf::RooProdPdf ( )

Default constructor.

Definition at line 83 of file RooProdPdf.cxx.

◆ RooProdPdf() [2/8]

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

Dummy constructor.

Definition at line 99 of file RooProdPdf.cxx.

◆ RooProdPdf() [3/8]

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.

◆ RooProdPdf() [4/8]

RooProdPdf::RooProdPdf ( const char *  name,

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.

Constructor from named argument list.

Parameters
[in]nameName used by RooFit
[in]titleTitle used for plotting
[in]fullPdfSetSet of "regular" PDFs that are normalised over all their observables
[in]argXOptional arguments according to table below.
Argument Description
Conditional(pdfSet,depSet,depsAreCond=false) Add PDF to product with condition that it only be normalized over specified observables. Any remaining observables will be conditional observables. (Setting depsAreCond to true inverts this, so the observables in depSet will be the 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:

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

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

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

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 \( G(y) \).

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.
