RooAbsPdf Class Reference

RooAbsPdf is the abstract interface for all probability density functions The class provides hybrid analytical/numerical normalization for its implementations, error tracing and a MC generator interface.

A minimal implementation of a PDF class derived from RooAbsPdf should overload the evaluate() function. This functions should return PDFs value.

Normalization/Integration

Although the normalization of a PDF is an integral part of a probability density function, normalization is treated separately in RooAbsPdf. The reason is that a RooAbsPdf object is more than a PDF: it can be a building block for a more complex, composite PDF if any of its variables are functions instead of variables. In such cases the normalization of the composite may not be simply the integral over the dependents of the top level PDF as these are functions with potentially non-trivial Jacobian terms themselves. Therefore

--> No explicit attempt should be made to normalize the functions output in evaluate().**

In addition, RooAbsPdf objects do not have a static concept of what variables are parameters and what variables are dependents (which need to be integrated over for a correct PDF normalization). Instead the choice of normalization is always specified each time a normalized values is requested from the PDF via the getVal() method.

RooAbsPdf manages the entire normalization logic of each PDF with help of a RooRealIntegral object, which coordinates the integration of a given choice of normalization. By default, RooRealIntegral will perform a fully numeric integration of all dependents. However, PDFs can advertise one or more (partial) analytical integrals of their function, and these will be used by RooRealIntegral, if it determines that this is safe (i.e. no hidden Jacobian terms, multiplication with other PDFs that have one or more dependents in commen etc)

To implement analytical integrals, two functions must be implemented. First,

Int_t getAnalyticalIntegral(const RooArgSet& integSet, RooArgSet& anaIntSet)

advertises the analytical integrals that are supported. 'integSet' is the set of dependents for which integration is requested. The function should copy the subset of dependents it can analytically integrate to anaIntSet and return a unique identification code for this integration configuration. If no integration can be performed, zero should be returned. Second,

Double_t analyticalIntegral(Int_t code)

Implements the actual analytical integral(s) advertised by getAnalyticalIntegral. This functions will only be called with codes returned by getAnalyticalIntegral, except code zero.

The integration range for real each dependent to be integrated can be obtained from the dependents' proxy functions min() and max(). Never call these proxy functions for any proxy not known to be a dependent via the integration code. Doing so may be ill-defined, e.g. in case the proxy holds a function, and will trigger an assert. Integrated category dependents should always be summed over all of their states.

Direct generation of observables

Any PDF dependent can be generated with the accept/reject method, but for certain PDFs more efficient methods may be implemented. To implement direct generation of one or more observables, two functions need to be implemented, similar to those for analytical integrals:

Int_t getGenerator(const RooArgSet& generateVars, RooArgSet& directVars) and void generateEvent(Int_t code)

The first function advertises observables that can be generated, similar to the way analytical integrals are advertised. The second function implements the generator for the advertised observables

The generated dependent values should be store in the proxy objects. For this the assignment operator can be used (i.e. xProxy = 3.0 ). Never call assign to any proxy not known to be a dependent via the generation code. Doing so may be ill-defined, e.g. in case the proxy holds a function, and will trigger an assert

Generate a new dataset containing the specified variables with events sampled from our distribution.

Generate the specified number of events or expectedEvents() if not specified.

Parameters
[in]whatVarsChoose variables in which to generate events. Variables not listed here will remain constant and not be used for event generation.
[in]argxxOptional RooCmdArg() to change behaviour of generate
Returns
RooDataSet *, owned by caller.

Any variables of this PDF that are not in whatVars will use their current values and be treated as fixed parameters. Returns zero in case of an error.

Type of CmdArg Effect on generate
Name(const char* name) Name of the output dataset
Verbose(Bool_t flag) Print informational messages during event generation
NumEvent(int nevt) Generate specified number of events
Extended() The actual number of events generated will be sampled from a Poisson distribution with mu=nevt. For use with extended maximum likelihood fits
GenBinned(const char* tag) Use binned generation for all component pdfs that have 'setAttribute(tag)' set
AutoBinned(Bool_t flag) Automatically deploy binned generation for binned distributions (e.g. RooHistPdf, sums and products of RooHistPdfs etc)
Note
Datasets that are generated in binned mode are returned as weighted unbinned datasets
AllBinned() As above, but for all components.
Note
The notion of components is only meaningful for simultaneous PDFs as binned generation is always executed at the top-level node for a regular PDF, so for those it only mattes that the top-level node is tagged.
ProtoData(const RooDataSet& data, Bool_t randOrder) Use specified dataset as prototype dataset. If randOrder in ProtoData() is set to true, the order of the events in the dataset will be read in a random order if the requested number of events to be generated does not match the number of events in the prototype dataset.
Note
If ProtoData() is used, the specified existing dataset as a prototype: the new dataset will contain the same number of events as the prototype (unless otherwise specified), and any prototype variables not in whatVars will be copied into the new dataset for each generated event and also used to set our PDF parameters. The user can specify a number of events to generate that will override the default. The result is a copy of the prototype dataset with only variables in whatVars randomized.

◆ plotOn() [3/3]

RooPlot * RooAbsPdf::plotOn ( RooPlot frame,
RooLinkedList cmdList 
) const
virtual

Plot (project) PDF on specified frame.

If a PDF is plotted in an empty frame, it will show a unit normalized curve in the frame variable, taken at the present value of other observables defined for this PDF.

If a PDF is plotted in a frame in which a dataset has already been plotted, it will show a projected curve integrated over all variables that were present in the shown dataset except for the one on the x-axis. The normalization of the curve will also be adjusted to the event count of the plotted dataset. An informational message will be printed for each projection step that is performed

This function takes the following named arguments

Type of CmdArg Projection control
Slice(const RooArgSet& set) Override default projection behaviour by omitting observables listed in set from the projection, resulting a 'slice' plot. Slicing is usually only sensible in discrete observables
Project(const RooArgSet& set) Override default projection behaviour by projecting over observables given in set and complete ignoring the default projection behavior. Advanced use only.
ProjWData(const RooAbsData& d) Override default projection technique (integration). For observables present in given dataset projection of PDF is achieved by constructing an average over all observable values in given set. Consult RooFit plotting tutorial for further explanation of meaning & use of this technique
ProjWData(const RooArgSet& s, const RooAbsData& d) As above but only consider subset 's' of observables in dataset 'd' for projection through data averaging
ProjectionRange(const char* rn) Override default range of projection integrals to a different range specified by given range name. This technique allows you to project a finite width slice in a real-valued observable
NormRange(const char* name) Calculate curve normalization w.r.t. only in specified ranges.
Note
A Range() by default implies a NormRange() on the same range, but this option allows to override the default, or specify a normalization ranges when the full curve is to be drawn
Misc content control
Normalization(Double_t scale, ScaleType code) Adjust normalization by given scale factor. Interpretation of number depends on code: Relative: relative adjustment factor, NumEvent: scale to match given number of events.
Name(const chat* name) Give curve specified name in frame. Useful if curve is to be referenced later
Asymmetry(const RooCategory& c) Show the asymmetry of the PDF in given two-state category \( \frac{F(+)-F(-)}{F(+)+F(-)} \) rather than the PDF projection. Category must have two states with indices -1 and +1 or three states with indeces -1,0 and +1.
ShiftToZero(Bool_t flag) Shift entire curve such that lowest visible point is at exactly zero. Mostly useful when plotting -log(L) or \( \chi^2 \) distributions
AddTo(const char* name, double_t wgtSelf, double_t wgtOther)

Add constructed projection to already existing curve with given name and relative weight factors

Plotting control
LineStyle(Int_t style) Select line style by ROOT line style code, default is solid
LineColor(Int_t color) Select line color by ROOT color code, default is blue
LineWidth(Int_t width) Select line with in pixels, default is 3
FillStyle(Int_t style) Select fill style, default is not filled. If a filled style is selected, also use VLines() to add vertical downward lines at end of curve to ensure proper closure
FillColor(Int_t color) Select fill color by ROOT color code
Range(const char* name) Only draw curve in range defined by given name
Range(double lo, double hi) Only draw curve in specified range
VLines() Add vertical lines to y=0 at end points of curve
Precision(Double_t eps) Control precision of drawn curve w.r.t to scale of plot, default is 1e-3. Higher precision will result in more and more densely spaced curve points A negative precision value will disable adaptive point spacing and restrict sampling to the grid point of points defined by the binning of the plotted observabled (recommended for expensive functions such as profile likelihoods)
Invisible(Bool_t flag) Add curve to frame, but do not display. Useful in combination AddTo()

◆ specialGeneratorConfig() [2/2]

RooNumGenConfig * RooAbsPdf::specialGeneratorConfig ( Bool_t  createOnTheFly)

Returns the specialized integrator configuration for this RooAbsReal.

If this object has no specialized configuration, a null pointer is returned, unless createOnTheFly is kTRUE in which case a clone of the default integrator configuration is created, installed as specialized configuration, and returned

◆ syncNormalization()

Bool_t RooAbsPdf::syncNormalization ( const RooArgSet nset,
Bool_t  adjustProxies = kTRUE 
) const
protectedvirtual

Verify that the normalization integral cached with this PDF is valid for given set of normalization observables.

If not, the cached normalization integral (if any) is deleted and a new integral is constructed for use with 'nset' Elements in 'nset' can be discrete and real, but must be lvalues

For functions that declare to be self-normalized by overloading the selfNormalized() function, a unit normalization is always constructed
