Detailed Description

Gamma Distributed Random Variable

GammaVariable defines a random variable with gamma distribution.

This class supports the creation of objects that return random numbers from a fixed gamma distribution. It also supports the generation of single random numbers from various gamma distributions.

The probability density function is defined over the interval [0,+inf) as: where and

Constructor & Destructor Documentation

ns3::GammaVariable::GammaVariable

(

)

Constructs a gamma random variable with alpha = 1.0 and beta = 1.0

ns3::GammaVariable::GammaVariable	(	double	alpha,
		double	beta
	)

Parameters:

	alpha	alpha parameter of the gamma distribution
	beta	beta parameter of the gamma distribution

Member Function Documentation

double ns3::GammaVariable::GetValue	(	double	alpha,
		double	beta
	)			const

Returns a gamma random distributed double with parameters alpha and beta.

Parameters:

	alpha	alpha parameter of the gamma distribution
	beta	beta parameter of the gamma distribution

Returns:

A floating point random value

double ns3::GammaVariable::GetValue

(

void

)

const

call RandomVariable::GetValue

Returns:

A floating point random value

Note: we have to re-implement this method here because the method is overloaded below for the two-argument variant and the c++ name resolution rules don't work well with overloads split between parent and child classes.

Reimplemented from ns3::RandomVariable.
