RooDataHist Class Reference

RooDataSet is a container class to hold N-dimensional binned data.

Each bins central coordinates in N-dimensional space are represented by a RooArgSet of RooRealVar, RooCategory or RooStringVar objects, thus data can be binned in real and/or discrete dimensions

Constructor & Destructor Documentation

◆ RooDataHist() [1/9]

RooDataHist::RooDataHist ( )

Default constructor.

Definition at line 63 of file RooDataHist.cxx.

◆ RooDataHist() [2/9]

RooDataHist::RooDataHist ( const char *  name,
const char *  title,
const RooArgSet vars,
const char *  binningName = 0 
)

Constructor of an empty data hist from a RooArgSet defining the dimensions of the data space.

The range and number of bins in each dimensions are taken from getMin()getMax(),getBins() of each RooAbsArg representing that dimension.

For real dimensions, the fit range and number of bins can be set independently of the plot range and number of bins, but it is advisable to keep the ratio of the plot bin width and the fit bin width an integer value. For category dimensions, the fit ranges always comprises all defined states and each state is always has its individual bin

To effective achive binning of real dimensions with variable bins sizes, construct a RooThresholdCategory of the real dimension to be binned variably. Set the thresholds at the desired bin boundaries, and construct the data hist as function of the threshold category instead of the real variable.

Definition at line 103 of file RooDataHist.cxx.

RooDataHist::RooDataHist ( const char *  name,
const char *  title,

const RooAbsData data,
Double_t  wgt = 1.0 
)

Constructor of a data hist from an existing data collection (binned or unbinned) The RooArgSet 'vars' defines the dimensions of the histogram.

The range and number of bins in each dimensions are taken from getMin()getMax(),getBins() of each RooAbsArg representing that dimension.

For real dimensions, the fit range and number of bins can be set independently of the plot range and number of bins, but it is advisable to keep the ratio of the plot bin width and the fit bin width an integer value. For category dimensions, the fit ranges always comprises all defined states and each state is always has its individual bin

To effective achive binning of real dimensions with variable bins sizes, construct a RooThresholdCategory of the real dimension to be binned variably. Set the thresholds at the desired bin boundaries, and construct the data hist as function of the threshold category instead of the real variable.

If the constructed data hist has less dimensions that in source data collection, all missing dimensions will be projected.

const RooCmdArg arg6 = RooCmdArg(),
const RooCmdArg arg7 = RooCmdArg(),
const RooCmdArg arg8 = RooCmdArg() 
)

Constructor of a binned dataset from a RooArgSet defining the dimensions of the data space.

The range and number of bins in each dimensions are taken from getMin() getMax(),getBins() of each RooAbsArg representing that dimension.

This constructor takes the following optional arguments

Import(TH1&, Bool_t impDens) – Import contents of the given TH1/2/3 into this binned dataset. The ranges and binning of the binned dataset are automatically adjusted to match those of the imported histogram.

Please note: for TH1& with unequal binning only, you should decide if you want to import the absolute bin content, or the bin content expressed as density. The latter is default and will result in the same histogram as the original TH1. For certain type of bin contents (containing efficiencies, asymmetries, or ratio is general) you should import the absolute value and set impDens to kFALSE

Weight(Double_t) – Apply given weight factor when importing histograms

Index(RooCategory&) – Prepare import of multiple TH1/1/2/3 into a N+1 dimensional RooDataHist where the extra discrete dimension labels the source of the imported histogram If the index category defines states for which no histogram is be imported the corresponding bins will be left empty.

Import(const char*, TH1&) – Import a THx to be associated with the given state name of the index category specified in Index(). If the given state name is not yet defined in the index category it will be added on the fly. The import command can be specified multiple times. Import(map<string,TH1*>&) – As above, but allows specification of many imports in a single operation

protected

Constructor of a data hist from (part of) an existing data hist.

The dimensions of the data set are defined by the 'vars' RooArgSet, which can be identical to 'dset' dimensions, or a subset thereof. Reduced dimensions will be projected in the output data hist. The optional 'cutVar' formula variable can used to select the subset of bins to be copied.

For most uses the RooAbsData::reduce() wrapper function, which uses this constructor, is the most convenient way to create a subset of an existing data

◆ weight() [2/2]

Double_t RooDataHist::weight ( const RooArgSet bin,
Int_t  intOrder = 1,
Bool_t  correctForBinSize = kFALSE,

Return the weight at given coordinates with optional interpolation.

If intOrder is zero, the weight for the bin enclosing the coordinates contained in 'bin' is returned. For higher values, the result is interpolated in the real dimensions of the dataset
