Detailed Description

Description of the class TCustomDistribution.

This class allows to define a discrete distribution of probabilities by associating a list of "labels" with a list of frequencies. The labels are real numbers, but no order is assumed between them, i.e. one can't say that "label 1.0 is smaller than label 2.0". The consequence is that the notions of Probability Density Function and Cumulative Distribution Function are irrelevant and the functions getPDF, getCDF and getInvCDF don't work the same as for TStochasticAttribute objects:

getPDF: returns the probability of the given label;
getCDF: returns nothing;
getInvCDF: returns a label drawn from a "pseudo-cumulative" distribution function.

Constructor & Destructor Documentation

◆ TCustomDistribution() [1/3]

URANIE::DataServer::TCustomDistribution::TCustomDistribution ( )

Default constructor.

Referenced by ClassImp().

◆ TCustomDistribution() [2/3]

URANIE::DataServer::TCustomDistribution::TCustomDistribution ( TString name )

Constructor by name only.

Parameters

name	(TString) Name of the attribute

◆ TCustomDistribution() [3/3]

URANIE::DataServer::TCustomDistribution::TCustomDistribution	(	TString	name,
		Int_t	nbValues,
		Double_t *	values,
		Double_t *	frequencies = `NULL`
	)

Constructor by name and statistics.

This constructor allows to define the distribution. The values are considered as labels, and not numerical values. This means that there is no need to sort them. The associated "frequencies" are given in a separated array. They are not probabilities as their sum does not need to be equal to 1. However, it is assumed that the distribution is complete, i.e. the discrete random variable can only take values from the one given.

Parameters

name	(TString) Name of the attribute
nbValues	(Int_t) Number of values taken by the discrete variable
values	(Double_t*) List of values taken by the discrete variable
frequencies	(Double_t*) List of the frequencies of each value. If NULL, the values are set to be equiprobable. Default = NULL.
