The class RooRealSumPdf implements a PDF constructed from a sum of functions:

\[ \mathrm{PDF}(x) = \frac{ \sum_{i=1}^{n-1} \mathrm{coef}_i * \mathrm{func}_i(x) + \left[ 1 - \sum_{i=1}^{n-1} \mathrm{coef}_i \right] * \mathrm{func}_n(x) } {\sum_{i=1}^{n-1} \mathrm{coef}_i * \int \mathrm{func}_i(x)dx + \left[ 1 - \sum_{i=1}^{n-1} \mathrm{coef}_i \right] * \int \mathrm{func}_n(x) dx } \]

where \(\mathrm{coef}_i\) and \(\mathrm{func}_i\) are RooAbsReal objects, and \( x \) is the collection of dependents. In the present version \(\mathrm{coef}_i\) may not depend on \( x \), but this limitation could be removed should the need arise.

If the number of coefficients is one less than the number of functions, the PDF is assumed to be normalised. Due to this additional constraint, \(\mathrm{coef}_n\) is computed from the other coefficients.

Extending the PDF

If an \( n^\mathrm{th} \) coefficient is provided, the PDF can be used as an extended PDF, i.e. the total number of events will be measured in addition to the fractions of the various functions. This requires setting the last argument of the constructor to true.

Note: For the RooAddPdf, the extension happens automatically.

Difference to RooAddPdf / RooRealSumFunc

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.

Constructor & Destructor Documentation

◆ RooRealSumPdf() [1/5]

RooRealSumPdf::RooRealSumPdf ( )

Default constructor coverity[UNINIT_CTOR].

Definition at line 71 of file RooRealSumPdf.cxx.

◆ RooRealSumPdf() [2/5]

RooRealSumPdf::RooRealSumPdf	(	const char *	name,
		const char *	title
	)

Constructor with name and title.

Definition at line 82 of file RooRealSumPdf.cxx.

◆ RooRealSumPdf() [3/5]

RooRealSumPdf::RooRealSumPdf	(	const char *	name,
		const char *	title,
		const RooArgList &	inFuncList,
		const RooArgList &	inCoefList,
		Bool_t	extended = `kFALSE`
	)

Constructor for a PDF from a list of functions and coefficients.

It implements

\[ \sum_i \mathrm{coef}_i \cdot \mathrm{func}_i, \]

if \( N_\mathrm{coef} = N_\mathrm{func} \). With extended=true, the coefficients can take any values. With extended=false, there is the danger of getting a degenerate minimisation problem because a PDF has to be normalised, which needs one degree of freedom less.

A plain (normalised) PDF can therefore be implemented with one less coefficient. RooFit then computes

\[ \sum_i^{N-1} \mathrm{coef}_i \cdot \mathrm{func}_i + (1 - \sum_i \mathrm{coef}_i ) \cdot \mathrm{func}_N, \]

if \( N_\mathrm{coef} = N_\mathrm{func} - 1 \).

All coefficients and functions are allowed to be negative but the sum (i.e. the PDF) is not, which is enforced at runtime.

Parameters

name	Name of the PDF
title	Title (for plotting)
inFuncList	List of functions to sum
inCoefList	List of coefficients
extended	Interpret as extended PDF (requires equal number of functions and coefficients)

Construct p.d.f consisting of \( \mathrm{coef}_1 * \mathrm{func}_1 + (1-\mathrm{coef}_1) * \mathrm{func}_2 \).

The input coefficients and functions are allowed to be negative but the resulting sum is not, which is enforced at runtime.
