Abstract base class for objects that represent a real value and implements functionality common to all real-valued objects such as the ability to plot them, to construct integrals of them, the ability to advertise (partial) analytical integrals etc.
Some member functions of RooAbsReal that take a RooCmdArg as argument also support keyword arguments. So far, this applies to RooAbsReal::plotOn, RooAbsReal::createHistogram, RooAbsReal::chi2FitTo, RooAbsReal::createChi2, RooAbsReal::createRunningIntegral and RooAbsReal::createIntegral For example, the following code is equivalent in PyROOT:
Implementation of RooAbsReal may be derived, thus no interface is provided to modify the contents.

Create an object that represents the integral of the function over one or more observables listed in iset.
The actual integration calculation is only performed when the return object is evaluated. The name of the integral object is automatically constructed from the name of the input function, the variables it integrates and the range integrates over. If nset is specified the integrand is request to be normalized over nset (only meaningful when the integrand is a pdf). If rangename is specified the integral is performed over the named range, otherwise it is performed over the domain of each integrated observable. If cfg is specified it will be used to configure any numeric integration aspect of the integral. It will not force the integral to be performed numerically, which is decided automatically by RooRealIntegral.

Create an object that represents the running integral of the function over one or more observables listed in iset, i.e.
The RooAbsReal::createRunningIntegral() function is pythonized with the command argument pythonization. The keywords must correspond to the CmdArgs of the function.
\[ \int_{x_\mathrm{lo}}^x f(x') \, \mathrm{d}x' \]
The actual integration calculation is only performed when the return object is evaluated. The name of the integral object is automatically constructed from the name of the input function, the variables it integrates and the range integrates over. The default strategy to calculate the running integrals is
The choice of strategy can be changed with the ScanAll() argument, which forces the use of the scanning technique implemented in RooNumRunningInt for all use cases, and with the ScanNone() argument which forces the 'integrate each evaluation' technique for all use cases. The sampling granularity for the scanning technique can be controlled with the ScanParameters technique which allows to specify the number of samples to be taken, and to which order the resulting running integral should be interpolated. The default values are 1000 samples and 2nd order interpolation.
The following named arguments are accepted
| Effect on integral creation | |
|---|---|
SupNormSet(const RooArgSet&) | Observables over which should be normalized in addition to the integration observables |
ScanParameters(Int_t nbins, Int_t intOrder) | Parameters for scanning technique of making CDF: number of sampled bins and order of interpolation applied on numeric cdf |
ScanNum() | Apply scanning technique if cdf integral involves numeric integration |

Propagates parameter uncertainties to an uncertainty estimate for this RooAbsReal.
Estimates the uncertainty \(\sigma_f(x;\theta)\) on a function \(f(x;\theta)\) represented by this RooAbsReal. Here, \(\theta\) is a vector of parameters with uncertainties \(\sigma_\theta\), and \(x\) are usually observables. The uncertainty is estimated by linearly propagating the parameter uncertainties using the correlation matrix from a fit result.
The square of the uncertainty on \(f(x;\theta)\) is calculated as follows:
\[ \sigma_f(x)^2 = \Delta f_i(x) \cdot \mathrm{Corr}_{i, j} \cdot \Delta f_j(x), \]
where \( \Delta f_i(x) = \frac{1}{2} \left(f(x;\theta_i + \sigma_{\theta_i}) - f(x; \theta_i - \sigma_{\theta_i}) \right) \) is the vector of function variations when changing the parameters one at a time, and \( \mathrm{Corr}_{i,j} = \left(\sigma_{\theta_i} \sigma_{\theta_j}\right)^{-1} \cdot \mathrm{Cov}_{i,j} \) is the correlation matrix from the fit result.

Evaluate object.
Returns either cached value or triggers a recalculation. The recalculation happens by calling getValV(), which in the end calls the virtual evaluate() functions of the respective PDFs.
| [in] | normalisationSet | getValV() reacts differently depending on the value of the normalisation set. If the set is nullptr, an unnormalised value is returned. |
To normalise the result properly, a RooArgSet has to be passed, which contains the variables to normalise over. These are integrated over their current ranges to compute the normalisation constant, and the unnormalised result is divided by this value.
Definition at line 103 of file RooAbsReal.h.
Calling RooAbsReal::getVal() with an r-value reference is a common performance trap, because this usually happens when implicitly constructing the RooArgSet to be used as the parameter (for example, in calls like pdf.getVal(x)).
Creating the RooArgSet can cause quite some overhead, especially when the evaluated object is just a simple variable. Even worse, many RooFit objects internally cache information using the uniqueId() of the normalization set as the key. So by constructing normalization sets in place, RooFits caching logic is broken.
To avoid these kind of problems, getVal() will just throw an error when it's called with an r-value reference. This also catches the cases where one uses it in Python, implicitly creating the normalization set from a Python list or set.

Log evaluation error message.
Evaluation errors may be routed through a different protocol than generic RooFit warning message (which go straight through RooMsgService) because evaluation errors can occur in very large numbers in the use of likelihood evaluations. In logEvalError mode, controlled by global method enableEvalErrorLogging() messages reported through this function are not printed but all stored in a list, along with server values at the time of reporting. Error messages logged in this way can be printed in a structured way, eliminating duplicates and with the ability to truncate the list by printEvalErrors. This is the standard mode of error logging during MINUIT operations. If enableEvalErrorLogging() is false, all errors reported through this method are passed for immediate printing through RooMsgService. A string with server names and values is constructed automatically for error logging purposes, unless a custom string with similar information is passed as argument.

| [in] | arg1,arg2,arg3,arg4,arg5,arg6,arg7,arg8,arg9,arg10 | Ordered arguments |
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
| 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. To pass multiple Slice() commands, please use the Slice(std::map<RooCategory*, std::string> const&) argument explained below. |
Slice(std::map<RooCategory*, std::string> const&) | Omits multiple categories from the projection, as explianed above. Can be used with initializer lists for convenience, e.g. pdf.plotOn(frame, Slice({{&tagCategory, "2tag"}, {&jetCategory, "3jet"}});
|
Project(const RooArgSet& set) | Override default projection behaviour by projecting over observables given in the set, 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 |
NumCPU(Int_t ncpu) | Number of CPUs to use simultaneously to calculate data-weighted projections (only in combination with ProjWData) |
| Misc content control | |
PrintEvalErrors(Int_t numErr) | Control number of p.d.f evaluation errors printed per curve. A negative value suppress output completely, a zero value will only print the error count per p.d.f component, a positive value is will print details of each error up to numErr messages per p.d.f component. |
EvalErrorValue(double value) | Set curve points at which (pdf) evaluation errors occur to specified value. By default the function value is plotted. |
Normalization(double scale, ScaleType code) | Adjust normalization by given scale factor. Interpretation of number depends on code:
|
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 [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) | Add constructed projection to already 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. |
| Plotting control | |
DrawOption(const char* opt) | Select ROOT draw option for resulting TGraph object. Currently supported options are "F" (fill), "L" (line), and "P" (points).
|
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 |
MarkerStyle(Int_t style) | Select the ROOT marker style, default is 21 |
MarkerColor(Int_t color) | Select the ROOT marker color, default is black |
MarkerSize(double size) | Select the ROOT marker size |
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. Add DrawOption("F") for filled drawing. |
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 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 |
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' |
VisualizeError() uses plotOnWithErrorBand(). Documentation of the latter:

Plotting engine function for internal use.
Plot ourselves on given frame. If frame contains a histogram, all dimensions of the plotted function that occur in the previously plotted dataset are projected via partial integration, otherwise no projections are performed. Optionally, certain projections can be performed by summing over the values present in a provided dataset ('projData'), to correctly project out data dependents that are not properly described by the PDF (e.g. per-event errors).
The functions value can be multiplied with an optional scale factor. The interpretation of the scale factor is unique for generic real functions, for PDFs there are various interpretations possible, which can be selection with 'stype' (see RooAbsPdf::plotOn() for details).
The default projection behaviour can be overridden by supplying an optional set of dependents to project via RooFit command arguments.

Plot function or PDF on frame with support for visualization of the uncertainty encoded in the given fit result fr.
| [in] | frame | RooPlot to plot on |
| [in] | fr | The RooFitResult, where errors can be extracted |
| [in] | Z | The desired significance (width) of the error band |
| [in] | params | If non-zero, consider only the subset of the parameters in fr for the error evaluation |
| [in] | argList | Optional RooCmdArg that can be applied to a regular plotOn() operation |
| [in] | linMethod | By default (linMethod=true), a linearized error is shown. |
The linearized error is calculated as follows:
\[ \mathrm{error}(x) = Z * F_a(x) * \mathrm{Corr}(a,a') * F_{a'}^\mathrm{T}(x), \]
where
\[ F_a(x) = \frac{ f(x,a+\mathrm{d}a) - f(x,a-\mathrm{d}a) }{2}, \]
with \( f(x) \) the plotted curve and \( \mathrm{d}a \) taken from the fit result, and \( \mathrm{Corr}(a,a') \) = the correlation matrix from the fit result, and \( Z \) = requested signifance ( \( Z \sigma \) band)
The linear method is fast (required 2*N evaluations of the curve, where N is the number of parameters), but may not be accurate in the presence of strong correlations (~>0.9) and at Z>2 due to linear and Gaussian approximations made
Alternatively, a more robust error is calculated using a sampling method. In this method a number of curves is calculated with variations of the parameter values, as drawn from a multi-variate Gaussian p.d.f. that is constructed from the fit results covariance matrix. The error(x) is determined by calculating a central interval that capture N% of the variations for each value of x, where N% is controlled by Z (i.e. Z=1 gives N=68%). The number of sampling curves is chosen to be such that at least 30 curves are expected to be outside the N% interval, and is minimally 100 (e.g. Z=1->Ncurve=100, Z=2->Ncurve=659, Z=3->Ncurve=11111) 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.
