Abstract interface for all probability density functions.
RooAbsPdf is the base class for all probability density functions (PDFs). The class provides hybrid analytical/numerical normalization for its implementations, error tracing, and a Monte Carlo generator interface.
A minimal implementation of a PDF class derived from RooAbsPdf should override the evaluate()
function. This function should return the PDF's value (which does not need to be normalised).
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 PDF may not simply be integral over the dependents of the top-level PDF: these are functions with potentially non-trivial Jacobian terms themselves.
evaluate()
function.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 value is requested from the PDF via the getVal() method.
RooAbsPdf manages the entire normalization logic of each PDF with the help of a RooRealIntegral object, which coordinates the integration of a given choice of normalization. By default, RooRealIntegral will perform an entirely 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 common, etc).
To implement analytical integrals, two functions must be implemented. First,
should return 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,
implements the actual analytical integral(s) advertised by getAnalyticalIntegral()
. This function will only be called with codes returned by getAnalyticalIntegral()
, except code zero.
The integration range for each dependent to be integrated can be obtained from the dependent's 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.
Distributions for any PDF 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:
and
The first function advertises observables, for which distributions can be generated, similar to the way analytical integrals are advertised. The second function implements the actual generator for the advertised observables.
The generated dependent values should be stored 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.
To speed up computations with large numbers of data events in unbinned fits, it is beneficial to override computeBatch()
. Like this, large spans of computations can be done, without having to call evaluate()
for each single data event. computeBatch()
should execute the same computation as evaluate()
, but it may choose an implementation that is capable of SIMD computations. If computeBatch is not implemented, the classic and slower evaluate()
will be called for each data event.
Some member functions of RooAbsPdf that take a RooCmdArg as argument also support keyword arguments. So far, this applies to RooAbsPdf::fitTo, RooAbsPdf::plotOn, RooAbsPdf::generate, RooAbsPdf::paramOn, RooAbsPdf::createCdf, RooAbsPdf::generateBinned, RooAbsPdf::prepareMultiGen and RooAbsPdf::createNLL. For example, the following code is equivalent in PyROOT:

Create a cumulative distribution function of this p.d.f in terms of the observables listed in iset.
If no nset argument is given the c.d.f normalization is constructed over the integrated observables, so that its maximum value is precisely 1. It is also possible to choose a different normalization for multi-dimensional p.d.f.s: eg. for a pdf f(x,y,z) one can construct a partial cdf c(x,y) that only when integrated itself over z results in a maximum value of 1. To construct such a cdf pass z as argument to the optional nset argument

Construct representation of -log(L) of PDF with given dataset.
If dataset is unbinned, an unbinned likelihood is constructed. If the dataset is binned, a binned likelihood is constructed.
data | Reference to a RooAbsData object representing the dataset. |
cmdArgs | Variadic template arguments representing optional command arguments. You can pass either an arbitrary number of RooCmdArg instances or a single RooLinkedList that points to the RooCmdArg objects. |
CmdArgs_t | Template types for optional command arguments. Can either be an arbitrary number of RooCmdArg or a single RooLinkedList. |
The following named arguments are supported:
Type of CmdArg | Effect on NLL | ||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|
ConditionalObservables(Args_t &&... argsOrArgSet) | Do not normalize PDF over listed observables. Arguments can either be multiple RooRealVar or a single RooArgSet containing them. | ||||||||||||
Range(const char* name) | Fit only data inside range with given name. Multiple comma-separated range names can be specified. In this case, the unnormalized PDF \(f(x)\) is normalized by the integral over all ranges \(r_i\): \[ p(x) = \frac{f(x)}{\sum_i \int_{r_i} f(x) dx}. \] | ||||||||||||
Range(double lo, double hi) | Fit only data inside given range. A range named "fit" is created on the fly on all observables. | ||||||||||||
SumCoefRange(const char* name) | Set the range in which to interpret the coefficients of RooAddPdf components | ||||||||||||
NumCPU(int num, int istrat) | Parallelize NLL calculation on num CPUs
| ||||||||||||
EvalBackend(std::string const&) | Choose a likelihood evaluation backend:
| ||||||||||||
Optimize(bool flag) | Activate constant term optimization (on by default) | ||||||||||||
SplitRange(bool flag) | Use separate fit ranges in a simultaneous fit. Actual range name for each subsample is assumed to be rangeName_indexState , where indexState is the state of the master index category of the simultaneous fit. Using Range("range"), SplitRange() as switches, different ranges could be set like this: myVariable.setRange("range_pi0", 135, 210);
myVariable.setRange("range_gamma", 50, 210);
| ||||||||||||
Constrain(const RooArgSet&pars) | For p.d.f.s that contain internal parameter constraint terms (that is usually product PDFs, where one term of the product depends on parameters but not on the observable(s),), only apply constraints to the given subset of parameters. | ||||||||||||
ExternalConstraints(const RooArgSet& ) | Include given external constraints to likelihood by multiplying them with the original likelihood. | ||||||||||||
GlobalObservables(const RooArgSet&) | Define the set of normalization observables to be used for the constraint terms. If none are specified the constrained parameters are used. | ||||||||||||
GlobalObservablesSource(const char* sourceName) | Which source to prioritize for global observable values. Can be either:
| ||||||||||||
GlobalObservablesTag(const char* tagName) | Define the set of normalization observables to be used for the constraint terms by a string attribute associated with pdf observables that match the given tagName. | ||||||||||||
Verbose(bool flag) | Controls RooFit informational messages in likelihood construction | ||||||||||||
CloneData(bool flag) | Use clone of dataset in NLL (default is true).
| ||||||||||||
Offset(std::string const& mode) | Likelihood offsetting mode. Can be either:
| ||||||||||||
IntegrateBins(double precision) | In binned fits, integrate the PDF over the bins instead of using the probability density at the bin centre. This can reduce the bias observed when fitting functions with high curvature to binned data.
| ||||||||||||
ModularL(bool flag) | Enable or disable modular likelihoods, which will become the default in a future release. This does not change any user-facing code, but only enables a different likelihood class in the back-end. Note that this should be set to true for parallel minimization of likelihoods! Note that it is currently not recommended to use Modular likelihoods without any parallelization enabled in the minimization, since some features such as offsetting might not yet work in this case. |

Return the extended likelihood term ( \( N_\mathrm{expect} - N_\mathrm{observed} \cdot \log(N_\mathrm{expect} \)) of this PDF for the given number of observed events.
For successful operation, the PDF implementation must indicate that it is extendable by overloading canBeExtended()
, and must implement the expectedEvents()
function.
[in] | observed | The number of observed events. |
[in] | nset | The normalization set when asking the pdf for the expected number of events. |
[in] | observedSumW2 | The number of observed events when weighting with squared weights. If non-zero, the weight-squared error correction is applied to the extended term. |
[in] | doOffset | Offset the extended term by a counterterm where the expected number of events equals the observed number of events. This constant shift results in a term closer to zero that is approximately chi-square distributed. It is useful to do this also when summing multiple NLL terms to avoid numeric precision loss that happens if you sum multiple terms of different orders of magnitude. |
The weight-squared error correction works as follows: adjust poisson such that estimate of \(N_\mathrm{expect}\) stays at the same value, but has a different variance, rescale both the observed and expected count of the Poisson with a factor \( \sum w_{i} / \sum w_{i}^2 \) (the effective weight of the Poisson term), i.e., change \(\mathrm{Poisson}(N_\mathrm{observed} = \sum w_{i} | N_\mathrm{expect} )\) to \( \mathrm{Poisson}(\sum w_{i} \cdot \sum w_{i} / \sum w_{i}^2 | N_\mathrm{expect} \cdot \sum w_{i} / \sum w_{i}^2 ) \), weighted by the effective weight \( \sum w_{i}^2 / \sum w_{i} \) in the likelihood. Since here we compute the likelihood with the weight square, we need to multiply by the square of the effective weight:
The extended term for the likelihood weighted by the square of the weight will be then:
\( \left(\sum w_{i}^2 / \sum w_{i}\right)^2 \cdot W_\mathrm{expect} - (\sum w_{i}^2 / \sum w_{i})^2 \cdot W_\mathrm{observed} \cdot \log{W_\mathrm{expect}} \)
aund this is using the previous expressions for \( W_\mathrm{expect} \) and \( W_\mathrm{observed} \):
\( \sum w_{i}^2 / \sum w_{i} \cdot N_\mathrm{expect} - \sum w_{i}^2 \cdot \log{W_\mathrm{expect}} \)
Since the weights are constants in the likelihood we can use \(\log{N_\mathrm{expect}}\) instead of \(\log{W_\mathrm{expect}}\).
See also RooAbsPdf::extendedTerm(RooAbsData const& data, bool weightSquared, bool doOffset), which takes a dataset to extract \(N_\mathrm{observed}\) and the normalization set.

Return the extended likelihood term ( \( N_\mathrm{expect} - N_\mathrm{observed} \cdot \log(N_\mathrm{expect} \)) of this PDF for the given number of observed events.
This function is a wrapper around RooAbsPdf::extendedTerm(double, RooArgSet const *, double, bool) const, where the number of observed events and observables to be used as the normalization set for the pdf is extracted from a RooAbsData.
For successful operation, the PDF implementation must indicate that it is extendable by overloading canBeExtended()

Fit PDF to given dataset.
If dataset is unbinned, an unbinned maximum likelihood is performed. If the dataset is binned, a binned maximum likelihood is performed. By default the fit is executed through the MINUIT commands MIGRAD, HESSE in succession.
data | Reference to a RooAbsData object representing the dataset. |
cmdArgs | Variadic template arguments representing optional command arguments. You can pass either an arbitrary number of RooCmdArg instances or a single RooLinkedList that points to the RooCmdArg objects. |
nullptr
otherwise. The user takes ownership of the fit result.CmdArgs_t | Template types for optional command arguments. Can either be an arbitrary number of RooCmdArg or a single RooLinkedList. |
The following named arguments are supported:
Type of CmdArg | Options to control construction of -log(L) | ||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
All command arguments that can also be passed to the NLL creation method.
| |||||||||||
Options to control flow of fit procedure | |||||||||||

| ||||||||||
InitialHesse(bool flag) | Flag controls if HESSE before MIGRAD as well, off by default | ||||||||||
Optimize(bool flag) | Activate constant term optimization of test statistic during minimization (on by default) | ||||||||||

Save(bool flag) | Flag controls if RooFitResult object is produced and returned, off by default | ||||||||||
Strategy(Int_t flag) | Set Minuit strategy (0 to 2, default is 1) | ||||||||||
MaxCalls(int n) | Change maximum number of likelihood function calls from MINUIT (if n <= 0 , the default of 500 * #parameters is used) | ||||||||||
EvalErrorWall(bool flag=true) | When parameters are in disallowed regions (e.g. PDF is negative), return very high value to fitter to force it out of that region. This can, however, mean that the fitter gets lost in this region. If this happens, try switching it off. | ||||||||||
RecoverFromUndefinedRegions(double strength) | When PDF is invalid (e.g. parameter in undefined region), try to direct minimiser away from that region. | ||||||||||
SumW2Error(bool flag) | Apply correction to errors and covariance matrix. This uses two covariance matrices, one with the weights, the other with squared weights, to obtain the correct errors for weighted likelihood fits. If this option is activated, the corrected covariance matrix is calculated as \( V_\mathrm{corr} = V C^{-1} V \), where \( V \) is the original covariance matrix and \( C \) is the inverse of the covariance matrix calculated using the squared weights. This allows to switch between two interpretations of errors:
| ||||||||||
AsymptoticError() | Use the asymptotically correct approach to estimate errors in the presence of weights. This is slower but more accurate than SumW2Error . See also https://arxiv.org/abs/1911.01303). | ||||||||||
PrefitDataFraction(double fraction) | Runs a prefit on a small dataset of size fraction*(actual data size). This can speed up fits by finding good starting values for the parameters for the actual fit.
| ||||||||||
Options to control informational output | |||||||||||
Verbose(bool flag) | Flag controls if verbose output is printed (NLL, parameter changes during fit). | ||||||||||
Timer(bool flag) | Time CPU and wall clock consumption of fit steps, off by default. | ||||||||||
PrintLevel(Int_t level) | Set Minuit print level (-1 to 3, default is 1). At -1 all RooFit informational messages are suppressed as well. See RooMinimizer::PrintLevel for the meaning of the levels. | ||||||||||
Warnings(bool flag) | Enable or disable MINUIT warnings (enabled by default) | ||||||||||
PrintEvalErrors(Int_t numErr) | Control number of p.d.f evaluation errors printed per likelihood evaluation. A negative value suppresses output completely, a zero value will only print the error count per p.d.f component, a positive value will print details of each error up to numErr messages per p.d.f component. | ||||||||||
Parallelize(Int_t nWorkers) | Control global parallelization settings. Arguments 1 and above enable the use of RooFit's parallel minimization backend and uses the number given as the number of workers to use in the parallelization. -1 also enables RooFit's parallel minimization backend, and sets the number of workers to the number of available processes. 0 disables this feature. In case parallelization is requested, this option implies ModularL(true) in the internal call to the NLL creation method. | ||||||||||
ParallelGradientOptions(bool enable=true, int orderStrategy=0, int chainFactor=1) | Experimental - Control gradient parallelization settings. The first argument only disables or enables gradient parallelization, this is on by default. The second argument determines the internal partial derivative calculation ordering strategy. The third argument determines the number of partial derivatives that are executed per task package on each worker. | ||||||||||
ParallelDescentOptions(bool enable=false, int splitStrategy=0, int numSplits=4) | Experimental - Control settings related to the parallelization of likelihoods outside of the gradient calculation but in the minimization, most prominently in the linesearch step. The first argument this disables or enables likelihood parallelization. The second argument determines whether to split the task batches per event or per likelihood component. And the third argument how many events or respectively components to include in each batch. | ||||||||||
TimingAnalysis(bool flag) | Experimental - Log timings. This feature logs timings with NewStyle likelihoods on multiple processes simultaneously and outputs the timings at the end of a run to json log files, which can be analyzed with the RooFit::MultiProcess::HeatmapAnalyzer . Only works with simultaneous likelihoods. |

This function takes the following named arguments (for more arguments, see also RooAbsReal::plotOn(RooPlot*,const RooCmdArg&,const RooCmdArg&,const RooCmdArg&,const RooCmdArg&, const RooCmdArg&,const RooCmdArg&,const RooCmdArg&,const RooCmdArg&,const RooCmdArg&, const RooCmdArg&) const )
Type of argument | Controlling normalisation |
---|---|
NormRange(const char* name) | Calculate curve normalization w.r.t. specified range[s]. See the tutorial rf212_plottingInRanges_blinding.C
|
Normalization(double scale, ScaleType code) | Adjust normalization by given scale factor. Interpretation of number depends on code: |
Type of argument | Misc control |
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 indices -1,0 and +1. |
ShiftToZero(bool 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) | Create a projection of this PDF onto the x-axis, but instead of plotting it directly, add it to an existing curve with given name (and relative weight factors). |
Components(const char* names) | When plotting sums of PDFs, plot only the named components (e.g. only the signal of a signal+background model). |
Components(const RooArgSet& compSet) | As above, but pass a RooArgSet of the components themselves. |
Type of argument | Projection control |
Slice(const RooArgSet& set) | Override default projection behaviour by omitting observables listed in set from the projection, i.e. by not integrating over these. Slicing is usually only sensible in discrete observables, by e.g. creating a slice of the PDF at the current value of the category observable. |
Slice(RooCategory& cat, const char* label) | Override default projection behaviour by omitting the specified category observable from the projection, i.e., by not integrating over all states of this category. The slice is positioned at the given label value. Multiple Slice() commands can be given to specify slices in multiple observables, e.g. pdf.plotOn(frame, Slice(tagCategory, "2tag"), Slice(jetCategory, "3jet"));
|
Project(const RooArgSet& set) | Override default projection behaviour by projecting over observables given in set, completely 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) | When projecting the PDF onto the plot axis, it is usually integrated over the full range of the invisible variables. The ProjectionRange overrides this. This is useful if the PDF was fitted in a limited range in y, but it is now projected onto x. If |
Type of argument | 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. Multiple comma-separated ranges can be given. An empty string "" or nullptr means to use the default range of the variable. |
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 eps) | Control precision of drawn curve w.r.t to scale of plot, default is 1e-3. A 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 observable (recommended for expensive functions such as profile likelihoods) |
Invisible(bool flag) | Add curve to frame, but do not display. Useful in combination AddTo() |
VisualizeError(const RooFitResult& fitres, double Z=1, bool linearMethod=true) | Visualize the uncertainty on the parameters, as given in fitres, at 'Z' sigma. The linear method is fast but may not be accurate in the presence of strong correlations (~>0.9) and at Z>2 due to linear and Gaussian approximations made. Intervals from the sampling method can be asymmetric, and may perform better in the presence of strong correlations, but may take (much) longer to calculate
|
VisualizeError(const RooFitResult& fitres, const RooArgSet& param, double Z=1, bool linearMethod=true) | Visualize the uncertainty on the subset of parameters 'param', as given in fitres, at 'Z' sigma |

Prepare GenSpec configuration object for efficient generation of multiple datasets from identical specification.
Generate the specified number of events or expectedEvents() if not specified.
[in] | whatVars | Choose variables in which to generate events. Variables not listed here will remain constant and not be used for event generation. |
[in] | arg1,arg2,arg3,arg4,arg5,arg6 | Optional RooCmdArg() to change behaviour of generate(). |
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 flag) | Print informational messages during event generation |
NumEvents(int nevt) | Generate specified number of events |
Extended() | If no number of events to be generated is given, use expected number of events from extended likelihood term. This evidently only works for extended PDFs. |
GenBinned(const char* tag) | Use binned generation for all component pdfs that have 'setAttribute(tag)' set |
AutoBinned(bool flag) | Automatically deploy binned generation for binned distributions (e.g. RooHistPdf, sums and products of RooHistPdfs etc)
|
AllBinned() | As above, but for all components.
|
ProtoData(const RooDataSet& data, bool 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.
|
Depending on the fit model (if it is difficult to sample), it may be necessary to change generator settings. For the default generator (RooFoamGenerator), the number of samples or cells could be increased by e.g. using myPdf->specialGeneratorConfig()->getConfigSection("RooFoamGenerator").setRealValue("nSample",1e4);
The foam generator e.g. has the following config options:
The RooAbsPdf::generate() function is pythonized with the command argument pythonization. The keywords must correspond to the CmdArgs of the function.
The RooAbsPdf::prepareMultiGen() function is pythonized with the command argument pythonization. The keywords must correspond to the CmdArgs of the function.

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.
