Enumerator

kOnlyPrepStep

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer. This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

RooHist() [2/6]

RooHist::RooHist	(	double	nominalBinWidth,
		double	nSigma = 1,
		double	xErrorFrac = 1.0,
		double	scaleFactor = 1.0 )

Create an empty histogram that can be filled with the addBin() and addAsymmetryBin() methods.

Use the optional parameter to specify the confidence level in units of sigma to use for calculating error bars. The nominal bin width specifies the default used by addBin(), and is used to set the relative normalization of bins with different widths.

Definition at line 51 of file RooHist.cxx.

RooHist() [3/6]

RooHist::RooHist	(	const TH1 &	data,
		double	nominalBinWidth = 0,
		double	nSigma = 1,
		RooAbsData::ErrorType	etype = RooAbsData::Poisson,
		double	xErrorFrac = 1.0,
		bool	correctForBinWidth = true,
		double	scaleFactor = 1. )

Create a histogram from the contents of the specified TH1 object which may have fixed or variable bin widths.

Error bars are calculated using Poisson statistics. Prints a warning and rounds any bins with non-integer contents. Use the optional parameter to specify the confidence level in units of sigma to use for calculating error bars. The nominal bin width specifies the default used by addBin(), and is used to set the relative normalization of bins with different widths. If not set, the nominal bin width is calculated as range/nbins.

		double	nSigma = 1,
		RooAbsData::ErrorType	etype = RooAbsData::Poisson,
		double	xErrorFrac = 1.0,
		bool	efficiency = false,
		double	scaleFactor = 1.0 )

Create a histogram from the asymmetry between the specified TH1 objects which may have fixed or variable bin widths, but which must both have the same binning.

The asymmetry is calculated as (1-2)/(1+2). Error bars are calculated using Binomial statistics. Prints a warning and rounds any bins with non-integer contents. Use the optional parameter to specify the confidence level in units of sigma to use for calculating error bars. The nominal bin width specifies the default used by addAsymmetryBin(), and is used to set the relative normalization of bins with different widths. If not set, the nominal bin width is calculated as range/nbins.

		double	wgt1 = 1.0,
		double	wgt2 = 1.0,
		RooAbsData::ErrorType	etype = RooAbsData::Poisson,
		double	xErrorFrac = 1.0 )

Create histogram as sum of two existing histograms.

If Poisson errors are selected the histograms are added and Poisson confidence intervals are calculated for the summed content. If wgt1 and wgt2 are not 1 in this mode, a warning message is printed. If SumW2 errors are selected the histograms are added and the histograms errors are added in quadrature, taking the weights into account.

		double	xErrorFrac = 1.0,
		double	scaleFactor = 1.0,
		const RooArgSet *	normVars = nullptr,
		const RooFitResult *	fr = nullptr )

Create histogram from a pdf or function.

Errors are computed based on the fit result provided.

This signature is intended for unfolding/deconvolution scenarios, where a pdf is constructed as "data minus background" and is thus intended to be displayed as "data" (or at least data-like). Usage of this signature is triggered by the draw style "P" in RooAbsReal::plotOn.

More details.

Parameters

[in]	f	The function to be plotted.
[in]	x	The variable on the x-axis
[in]	xErrorFrac	Size of the error in x as a fraction of the bin width
[in]	scaleFactor	arbitrary scaling of the y-values
[in]	normVars	variables over which to normalize
[in]	fr	fit result

Member Function Documentation

AbstractMethod()

void TObject::AbstractMethod ( const char * method ) const

inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning

This interface is a legacy function that is no longer recommended to be used by new development code.

Note

The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

Divide()

void TGraphAsymmErrors::Divide ( const TH1 * pass, const TH1 * total, Option_t * opt = "cp" )

virtualinherited

Fill this TGraphAsymmErrors by dividing two 1-dimensional histograms pass/total.

This method serves two purposes:

1) calculating efficiencies:

The assumption is that the entries in "pass" are a subset of those in "total". That is, we create an "efficiency" graph, where each entry is between 0 and 1, inclusive.

If the histograms are not filled with unit weights, the number of effective entries is used to normalise the bin contents which might lead to wrong results.

\[\text{effective entries} = \frac{(\sum w_{i})^{2}}{\sum w_{i}^{2}} \]

The points are assigned a x value at the center of each histogram bin. The y values are \(\text{eff} = \frac{\text{pass}}{\text{total}}\) for all options except for the bayesian methods where the result depends on the chosen option.

If the denominator becomes 0 or pass > total, the corresponding bin is skipped.

2) calculating ratios of two Poisson means (option 'pois'):

The two histograms are interpreted as independent Poisson processes and the ratio

\[\tau = \frac{n_{1}}{n_{2}} = \frac{\varepsilon}{1 - \varepsilon} \]

with \(\varepsilon = \frac{n_{1}}{n_{1} + n_{2}}\). The histogram 'pass' is interpreted as \(n_{1}\) and the total histogram is used for \(n_{2}\).

The (asymmetric) uncertainties of the Poisson ratio are linked to the uncertainties of efficiency by a parameter transformation:

\[\Delta \tau_{low/up} = \frac{1}{(1 - \varepsilon)^{2}} \Delta \varepsilon_{low/up} \]

The x errors span each histogram bin (lowedge ... lowedge+width) The y errors depend on the chosen statistic methode which can be determined by the options given below. For a detailed description of the used statistic calculations please have a look at the corresponding functions!

Options:

• v : verbose mode: prints information about the number of used bins and calculated efficiencies with their errors
• cl=x : determine the used confidence level (0<x<1) (default is 0.683)
• cp : Clopper-Pearson interval (see TEfficiency::ClopperPearson)
• w : Wilson interval (see TEfficiency::Wilson)
• n : normal approximation propagation (see TEfficiency::Normal)
• ac : Agresti-Coull interval (see TEfficiency::AgrestiCoull)
• fc : Feldman-Cousins interval (see TEfficiency::FeldmanCousinsInterval)
• midp : Lancaster mid-P interval (see TEfficiency::MidPInterval)
• b(a,b): bayesian interval using a prior probability ~Beta(a,b); a,b > 0 (see TEfficiency::Bayesian)
• mode : use mode of posterior for Bayesian interval (default is mean)
• shortest: use shortest interval (done by default if mode is set)
• central: use central interval (done by default if mode is NOT set)
• pois: interpret histograms as poisson ratio instead of efficiency
• e0 : plot efficiency and interval for bins where total=0 (default is to skip them)

Note: Unfortunately there is no straightforward approach for determining a confidence interval for a given confidence level. The actual coverage probability of the confidence interval oscillates significantly according to the total number of events and the true efficiency. In order to decrease the impact of this oscillation on the actual coverage probability a couple of approximations and methodes has been developed. For a detailed discussion, please have a look at this statistical paper: http://www-stat.wharton.upenn.edu/~tcai/paper/Binomial-StatSci.pdf

UseCurrentStyle()

void TGraph::UseCurrentStyle ( )

overridevirtualinherited

Set current style settings in this object This function is called when either TCanvas::UseCurrentStyle or TROOT::ForceStyle have been invoked.

Reimplemented from TObject.

Warning()

void TObject::Warning ( const char * location, const char * fmt, ... ) const

virtualinherited

Issue warning message.

Use "location" to specify the method where the warning occurred. Accepts standard printf formatting arguments.

Write() [2/2]

Int_t TObject::Write ( const char * name = nullptr, Int_t option = 0, Int_t bufsize = 0 ) const

virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

• Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
• The TBuffer object is filled via the class::Streamer function.
• If the file is compressed (default) a second buffer is created to hold the compressed buffer.
• Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
• The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
