RooAddPdf Class Reference

RooAddPdf is an efficient implementation of a sum of PDFs of the form.

\[ \sum_{i=1}^{n} c_i * \mathrm{PDF}_i \]

or

\[ c_1*\mathrm{PDF}_1 + c_2*\mathrm{PDF}_2 + ... + (1-\sum_{i=1}^{n-1}c_i)*\mathrm{PDF}_n \]

The first form is for extended likelihood fits, where the expected number of events is \( \sum_i c_i \). The coefficients \( c_i \) can either be explicitly provided, or, if all components support extended likelihood fits, they can be calculated the contribution of each PDF to the total number of expected events.

In the second form, the sum of the coefficients is required to be one or less, and the coefficient of the last PDF is calculated from that condition.

It is also possible to parameterize the coefficients recursively

\[ c_1*\mathrm{PDF}_1 + (1-c_1)(c_2*\mathrm{PDF}_2 + (1-c_2)*(c_3*\mathrm{PDF}_3 + ...)) \]

In this form the sum of the coefficients is always less than 1.0 for all possible values of the individual coefficients between 0 and 1.

RooAddPdf relies on each component PDF to be normalized and will perform no normalization other than calculating the proper last coefficient \( c_n \), if requested. An (enforced) condition for this assumption is that each \( \mathrm{PDF}_i \) is independent of each \( c_i \).

Difference between RooAddPdf / RooRealSum{Func|Pdf}

  • RooAddPdf is a PDF of PDFs, i.e. its components need to be normalised and non-negative.
  • RooRealSumPdf is a PDF of functions, i.e., its components can be negative, but their sum cannot be. The normalisation is computed automatically, unless the PDF is extended (see above).
  • RooRealSumFunc is a sum of functions. It is neither normalised, nor need it be positive.

Definition at line 98 of file RooAddPdf.cxx.

◆ RooAddPdf() [2/6]

RooAddPdf::RooAddPdf ( const char *  name,

◆ RooAddPdf() [3/6]

RooAddPdf::RooAddPdf ( const char *  name,
const char *  title,

◆ RooAddPdf() [4/6]

RooAddPdf::RooAddPdf ( const char *  name,
const char *  title,
const RooArgList inPdfList 
)

Generic constructor from list of extended PDFs.

There are no coefficients as the expected number of events from each components determine the relative weight of the PDFs.

All PDFs must inherit from RooAbsPdf.

Definition at line 285 of file RooAddPdf.cxx.

◆ RooAddPdf() [5/6]

RooAddPdf::RooAddPdf ( const char *  name,
const char *  title,
const RooArgList inPdfList,
const RooArgList inCoefList,
Bool_t  recursiveFractions = kFALSE 
)

Generic constructor from list of PDFs and list of coefficients.

Each pdf list element (i) is paired with coefficient list element (i). The number of coefficients must be either equal to the number of PDFs, in which case extended MLL fitting is enabled, or be one less.

All PDFs must inherit from RooAbsPdf. All coefficients must inherit from RooAbsReal

If the recursiveFraction flag is true, the coefficients are interpreted as recursive coefficients as explained in the class description.

Definition at line 173 of file RooAddPdf.cxx.

◆ RooAddPdf() [6/6]

RooAddPdf::RooAddPdf ( const RooAddPdf other,
const char *  name = 0

Reimplemented from RooAbsPdf.

Definition at line 56 of file RooAddPdf.h.

◆ fixCoefNormalization()

void RooAddPdf::fixCoefNormalization ( const RooArgSet refCoefNorm)

By default the interpretation of the fraction coefficients is performed in the contextual choice of observables.

This makes the shape of the p.d.f explicitly dependent on the choice of observables. This method instructs RooAddPdf to freeze the interpretation of the coefficients to be done in the given set of observables. If frozen, fractions are automatically transformed from the reference normalization set to the contextual normalization set by ratios of integrals.

◆ fixCoefRange()

void RooAddPdf::fixCoefRange ( const char *  rangeName)

By default, fraction coefficients are assumed to refer to the default fit range.

This makes the shape of a RooAddPdf explicitly dependent on the range of the observables. Calling this function allows for a range-independent definition of the fractions, because it ties all coefficients to the given named range. If the normalisation range is different from this reference range, the appropriate fraction coefficients are automatically calculated from the reference fractions by integrating over the ranges, and comparing these integrals.

◆ getAnalyticalIntegralWN()

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

If any analytical integration is possible, return integration scenario code

RooAddPdf queries each 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 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 RooAddPdf.

Retrieve cache element for the computation of the PDF normalisation.

Parameters
[in]nsetCurrent normalisation set (integration over these variables yields 1).
[in]isetIntegration set. Variables to be integrated over (if integrations are performed).
[in]rangeNameReference range for the integrals.

If a cache element does not exist, create and fill it on the fly. The cache also contains

  • Supplemental normalization terms (in case not all added p.d.f.s have the same observables)
  • Projection integrals to calculate transformed fraction coefficients when a frozen reference frame is provided
  • Projection integrals for similar transformations when a frozen reference range is provided.
