RooAddModel Class Reference

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

\[ c_1 \cdot \mathrm{PDF}_1 + c_2 \cdot \mathrm{PDF}_2 + ... + c_n \cdot \mathrm{PDF}_n \]

or

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

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 from the contribution of each PDF to the total number of expected events.

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

RooAddModel 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 coefficient \( i \).

◆ fixCoefNormalization()

void RooAddModel::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 RooAddModel 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

Definition at line 187 of file RooAddModel.cxx.

◆ fixCoefRange()

void RooAddModel::fixCoefRange ( const char *  rangeName)

By default the interpretation of the fraction coefficients is performed in the default range.

This make the shape of a RooAddModel explicitly dependent on the range of the observables. To allow a range independent definition of the fraction this function instructs RooAddModel to freeze its interpretation in the given named range. If the current normalization range is different from the reference range, the appropriate fraction coefficients are automatically calculated from the reference fractions using ratios of integrals.

const char *  rangeName = nullptr 
) const
overridevirtual

Variant of getAnalyticalIntegral that is also passed the normalization set that should be applied to the integrand of which the integral is requested.

For certain operator p.d.f it is useful to overload this function rather than analyticalIntegralWN() as the additional normalization information may be useful in determining a more efficient decomposition of the requested integral.

Reimplemented from RooAbsReal.

Definition at line 456 of file RooAddModel.cxx.

◆ getCompIntList()

◆ getProjCache()

AddCacheElem * RooAddModel::getProjCache ( const RooArgSet nset,
const RooArgSet iset = nullptr 
) const
protected

Retrieve cache element with for calculation of p.d.f value with normalization set nset and integrated over iset in range 'rangeName'.

If cache element does not exist, create and fill it on the fly. The cache contains suplemental normalization terms (in case not all added p.d.f.s have the same observables), projection integrals to calculated transformed fraction coefficients when a frozen reference frame is provided and projection integrals for similar transformations when a frozen reference range is provided.
