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.
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.
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

Load generatedVars with the subset of directVars that we can generate events for, and return a code that specifies the generator algorithm we will use.
A code of zero indicates that we cannot generate any of the directVars (in this case, nothing should be added to generatedVars). Any non-zero codes will be passed to our generateEvent() implementation, but otherwise its value is arbitrary. The default implemetation of this method returns zero. Subclasses will usually implement this method using the matchArgs() methods to advertise the algorithms they provide.

Return pointer to RooAbsReal object that implements calculation of integral over observables iset in range rangeName, optionally taking the integrand normalized over observables nset.
Definition at line 401 of file RooAbsPdf.cxx.
Return current value, normalized by integrating over the observables in 'nset'.
If 'nset' is 0, the unnormalized value is returned. All elements of 'nset' must be lvalues
Unnormalized values are not cached. Doing so would be complicated as _norm->getVal() could spoil the cache and interfere with returning the cached return value. Since unnormalized calls are typically done in integration calls, there is no performance hit.

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.
|
| 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() |
