Detailed Description

CBShape PDF builder.

Build RooCBShape Pdf.

Config Directives:

/// configStr = CBShape ["<Optional Title>"]
/// x = AbsReal Def
/// mean = AbsReal Def
/// sigma = AbsReal Def
/// alpha = AbsReal Def
/// n = AbsReal Def

x is the default observable. mean is the mean of the pdf, sigma is the sigma of the pdf, alpha is the alpha of the pdf, n is the n of the pdf. All the variables can be RooRealVar or RooFormulaVar.

Constructor & Destructor Documentation

rarCBShape::rarCBShape

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 40 of file rarCBShape.cc.

References init().

  : rarBasePdf(),
    _x(0), _mean(0), _sigma(0), _alpha(0), _n(0)
{
  init();
}

rarCBShape::rarCBShape	(	const char *	configFile,
		const char *	configSec,
		const char *	configStr,
		rarDatasets *	theDatasets,
		RooDataSet *	theData,
		const char *	name,
		const char *	title
	)

Default ctor.

Parameters:

	configFile	The config file
	configSec	The config section
	configStr	The config string
	theDatasets	Available datasets
	theData	Default dataset for this PDF
	name	The name
	title	The title

The default ctor first initializes data members, _configFile, _configSec, _configStr, name, title, _x, _mean, _sigma, _alpha, _n, and then calls init.

Definition at line 61 of file rarCBShape.cc.

References init().

  : rarBasePdf(configFile, configSec, configStr,
               theDatasets, theData, name, title),
    _x(0), _mean(0), _sigma(0), _alpha(0), _n(0)
{
  init();
}

void rarCBShape::init

(

)

[protected, virtual]

Initial function called by ctor.

init is called by the ctor. It first creates the parameters by calling createAbsReal, and finally it builds the RooCBShape PDF.

Reimplemented from rarBasePdf.

Definition at line 81 of file rarCBShape.cc.

References _alpha, _mean, _n, rarBasePdf::_obsSet, rarBasePdf::_params, rarBasePdf::_pdfType, _sigma, rarBasePdf::_thePdf, _x, and rarConfig::createAbsReal().
