ParamHistFunc Class Reference

A class which maps the current values of a RooRealVar (or a set of RooRealVars) to one of a number of RooAbsReal (nominally RooRealVar):

ParamHistFunc: {val1, val2, ...} -> {gamma (RooRealVar)}

The intended interpretation is that each parameter in the range represent the height of a bin over the domain space.

The 'createParamSet' is an easy way to create these parameters from a set of observables. They are stored using the "TH1" ordering convention (as compared to the RooDataHist convention, which is used internally and one must map between the two).

All indices include '0':
\( \gamma_{i,j} \) = paramSet[ size(i)*j + i ]

ie assuming the dimensions are 5*5:
\( \gamma_{2,1} \) = paramSet[ 5*1 + 2 ] = paramSet[7]

◆ ParamHistFunc() [1/4]

Definition at line 62 of file ParamHistFunc.cxx.

◆ ParamHistFunc() [2/4]

ParamHistFunc::ParamHistFunc ( const char *  name,
const char *  title,
const RooArgList vars,
const RooArgList paramSet 
)

Create a function which returns binewise-values This class contains N RooAbsReals's, one for each bin from the given RooRealVar.

The value of the function in the ith bin is given by:

F(i) = gamma_i * nominal(i)

Where the nominal values are simply fixed numbers (default = 1.0 for all i)

Definition at line 81 of file ParamHistFunc.cxx.

◆ ParamHistFunc() [3/4]

ParamHistFunc::ParamHistFunc ( const char *  name,
const char *  title,
const RooArgList vars,
const RooArgList paramSet,
const TH1 Hist 
)

Create a function which returns bin-wise values.

This class allows to multiply bin contents of histograms with the values of a set of RooAbsReal.

The value of the function in the ith bin is given by:

\[ F(i) = \gamma_{i} * \mathrm{nominal}(i) \]

Where the nominal values are taken from the histogram, and the \( \gamma_{i} \) can be set from the outside.

◆ createParamSet() [2/3]

RooArgList ParamHistFunc::createParamSet ( RooWorkspace w,
const std::string &  Prefix,

static

Create the list of RooRealVar parameters which represent the height of the histogram bins.

The list 'vars' represents the observables (corresponding to histogram bins) that these newly created parameters will be mapped to. (ie, we create one parameter per observable in vars and per bin in each observable) Store them in a list using: _paramSet.add( createParamSet() ); This list is stored in the "TH1" index order

Definition at line 293 of file ParamHistFunc.cxx.

◆ createParamSet() [3/3]

RooArgList ParamHistFunc::createParamSet ( RooWorkspace w,
const std::string &  Prefix,
const RooArgList vars,
Double_t  gamma_min,
Double_t  gamma_max 
)
static

Create the list of RooRealVar parameters which scale the height of histogram bins.

The list vars represents the observables (corresponding to histogram bins) that these newly created parameters will be mapped to. I.e., we create one parameter per observable in vars and per bin in each observable.

The new parameters are initialised to 1 with an uncertainty of +/- 1., their range is set to the function arguments.

Store the parameters in a list using:

static RooArgList createParamSet(RooWorkspace &w, const std::string &, const RooArgList &Vars)
Create the list of RooRealVar parameters which represent the height of the histogram bins.
RooListProxy _paramSet
